Greatest Iranian Scholar Avicenna                                   


All the scholar and scientists are going to mention here are belonged to no one but to the whole world.   But some try to misrepresent where they were born and educated and grow up. We cannot say the Edison was an Arab or an Iranian though  he belongs to the world.  Saalad has been mentioning  about these people because they have said so much about the health issues such as eating right food and drinking a right water.  If a non Muslim wants to know a good typical Iranian Muslim then Avicenna (IBN SINA) is the one. He was born in Iran in 981 and died in 1037 was buried in Hamedan- Iran.He was the foremost:

  • physician.
  • Philosopher.
  • Astronomer.
  • Chemist.
  • Geologist.
  • Logician.
  • Paleontologist.
  • Mathematician.
  • Physicist.
  • Poet.
  • Psychologist.
  • Scientist.
  • Teacher.
  • He is the father of the modern medicine, father of the fundamental concept of momentum in physic and he is regarded as the pioneer of aromatherapy for his extraction of essential oils. He developed the concept of uniformitarianism and LAW of superposition in geology for which he is considered to be the father of geology.  He had nearly 20 Phd which he had received during his 56 years of living. Students from the third world countries come to study in Britain some of them take 12 years to get a Phd and when they complete their studies they will not return home to help their own people.

Regarding food Avicenna stated:

  " Your food is your medicine and your medicine is your food."

It is a simple statement but so much is in it , if  one is careful about what  one  eats then  one will stay healthy and never become ill. In the jangle Animals do not have  any doctor  or a surgery  to go to .  When they become ill they cure themselves by eating a right stuffs in the jangle and after a few days they become normal.   But if  they were bombarded by lots of chemicals and so many incompetent doctors hamper by prescribing a wrong treatments then the mater would be worse. As we hear that people go into a hospital to get a treatment for a minor surgery then they would be ended dead as a result of a medical negligence.

Avicenna said that Almighty created all beings and provided all their needs in the nature. If we are close to the nature we are safe.

He was a Tehrani

Shams al-Din Mohammad-e- Tabrizi was an Iranian sufi mystic born in the city of Tabriz in Iranian Azarbaijan. He introduced Mawlana Jalal ad-Din Mohammad Balkhi, usually known as RUMI  in the west, to Islamic mysticism, for which he was immortalized in RUMI's poetry collection Diwan-e-Shams-e-Tabrizi (The works of shams of Tabriz) Shams lived with Rumi for several years and they learned from each other and some of the Rumi 's followers did not like Shams therefore they made life difficult for Shams therefore he left Rumi and returned to Khoy -Iran and died there his Tomb has been nominated as a World Cultural Heritage Centre by UNESCO.  


As the years passed, Rumi attributed more and more of his own poetry to SHAMS as a sign of admiration, love and respect for his departed friend and master. Indeed, it quickly becomes clear in reading RUMI that Shams was elevated to a symbol of God's love for mankind, and that Shams was a sun (Shams in Arabic means SUN) shining the Light of God on Rumi.

Shams written a book called MAQALAT which contains some spiritual advice. Some of them are:

  • Blessing is excess, so to speak an excess of everything. Do not be content with being of Faqih (religious scholar), say I want more- more than being a Sufi (a mystic), more than being a mystic more than each thing that comes before you.
  • All the corruption in the world arises from this - someone believe in someone out of imitation or disbelieved in someone out of imitation.
  • A good man complains of no one; he does not look to faults.
  • Joy is like pure clear water; wherever it flows, wondrous blossoms grow... Sorrow is like a black flood; wherever it flows it wilts the blossoms.
  • And the Persian language, how did it happen? With so much elegance and goodness such that the meanings and elegance that is found in the Persian language is not found in Arabic.  

Omar KHayam - Born in Neyshapur- Iran 1123, was a:

1) Persian Polymath,
2) Mathematician
3) Philosopher
4) Astronomer of the medieval period.
5) Poet
6) Musician
7) Physicist


He has also become established as one of the major mathematicians and astronomers of the medieval period. Recognized as the author of the most important treatise on Algebra before modern times as reflected in his Treatise on Demonstration of Problems of Algebra giving a geometirc method for solving cubic equations by intersecting a hyperbola with a circle. He also contributed to calendar reform and may have proposed a heliocentric theory well before Copernicus. His significance as a philosopher and teacher, and his few remaining philosophical works, have not received the same attention as his scientific and poetic writings. Zamakhshari referred to him as "the philosopher of the world" Many sources have also testified that he taught for decades the philosophy of IBN SINA in Nishapur where Khayam lived most of his life, breathed his last, and was buried and where his mausoleum remains today a masterpiece of Iranian architecture visited by many people every year.


Outside Iran and Persian speaking countries, Khayyam has had impact on literature and societies through translation and works of scholars. The greatest such impact was in English-speaking countries; the English scholar Thomas Hyde (1636-1703) was the first non-Persian to study him. However the most influential of all was Edward FitzGerald (1809-1883) who made Khayyam the most famous poet of the East in the West through his celebrated translation and adaptations of Khyyam's rather small number of quatrains (RUBAIYAAT) in Rubaiyat of Omar Khayyam. His poems are misunderstood in the west. He is using wine as a metaphor and symbol not as Alcoholic drink.


Salman Farsi- One of the greatest follower of Islam

Salman:                        "When you are still hungry stop eating." 

                             This is to say that never eat till you are absolutely full up.

                            "Eat in a right time regularly with small amount of food"

    "Eart slowly and chew your food properly"

                                    "After eating wait calm half an hour so that your food digest"



Salman the Persian

was born with the Persian name ROUZBEH in the city of Kazerun in Fars, Iran. he grew up in the town of Isfahan in Persian, in the village of Jayyan. His father was the Dihqan (Chief of Agriculture) of the village. He was a  follower of  the Zartosht, believing in one God  the oldest religion of the world. He was the richest person there and had the biggest house. His father loved him, more than he loved any other. Salman was educated person. As time went by, his love for Salman became strong and over powering that he feared to lose him or have anything happen to him. So he kept him at home, a virtual prisoner, in the same way that young girl were kept.   Salam's father had a vast estate, which yield an abundant supply of crops. He himself looked after the estate and gathered harvest. One day as he went about his duties as Dihqan of the village, he said to Salman, " My son, as you see I am too busy to go out to the estate now. Go and look after matters there for me today." On the way to estate Salman passes a Christian church and heard voices raised in prayer, which attracted his attention. He did not know anything about Christianity or for that matter, about the followers of any other religion. His father had kept him in the house away from people. When he heard the voice of the Christianity, he entered the church to see what they were doing. He was impressed by their manner of praying and felt drawn to their religion. He said: "this religion is better than ours I shall not leave them until the sunset"." Salman asked and was told that the Christian religion originated in Syria. He did not go to his father 's estate that day and at night, he returned home. His father met him and asked where he had been. Salman told him about his meeting with the Christians and how he was impressed by their religion. His father was dismayed and said: " My son, there is nothing good in that religion. Your religion and the religion of your forefathers is better." Salman replied: "no  their religion is better than ours." His father became upset and afraid that Salman would leave their religion. So he kept Salman locked up in the house and sackled his feet. Salman managed to send a message to the Christians, asking them to inform him of any caravans going to Syria. Before long they  contacted him with the information he wanted. He broke the fetters and escaped his father's estate to join the caravan to Syria. When he reached there, he asked regarding the leading person in the Christian religion and was directed to the bishop of the church. He went up to him and said: " I want to become a Christian and would like to attach myself to your service, learn from you and pray with you.

The Bishop agreed and Salman entered the church in his service. Salman soon found out, however, that the bishop was corrupt like some of the ministers today in all religions are corrupt. He was traveling he arrived in the Arabian land and met the Prophet of Islam who had a reputation for strict honesty, one who would accept a gift but would never consume Charity for himself.  Salman became Muslim and said I am son of Islam from children of ADAM.

Salman was literate person and was very intelligent who the Prophet of Islam said Salman is from y family. All Muslims believe that Salman was one of the greatest followers of Islam.

All the Iranian are proud of Salman Farsi.

Khajeh al- Nasir Tusi


Muhammad ibn Muhammad ibn Hasan Tūsī was (born 18 February 1201 in Tus, Khorasan – 26 June 1274 in al-Kāżimiyyah, Baghdad), better known as Nasīr al-Dīn al-Tūsī or simply Tusi in the West),

 He was:

 1)   A Polymath;

2)   Prolific writer;

3)   Astronomer;

4)   Biologist;

5)   Chemist;

6)   Theologian;

7)   Musician.

 Nasir al-Din Tusi was born in the city of Tus in medieval Khorasan (now in north-eastern Iran) in the year 1201 and began his studies at an early age. In Hamadan and Tus he studied the Qur'an, Hadith, Shi'a jurisprudence, logic, philosophy, mathematics, medicine and astronomy.

He was apparently born into an Ismaili Shī‘ah family and lost his father at a young age. Fulfilling the wish of his father, the young Muhammad took learning and scholarship very seriously and traveled far and wide to attend the lectures of renowned scholars and acquire the knowledge which; guides people to the happiness of the next world. At a young age he moved to Nishapur to study philosophy under Farid al-Din Damad and mathematics under Muhammad Hasib. He met also Farid al-Din al-'Attar, the legendary Sufi master who was later killed by Mongol invaders and attended the lectures of Qutb al-Din al-Misri.

In Mawsil he studied mathematics and astronomy with Kamal al-Din Yunus (d. 639/1242). Later on he corresponded with al-Qunawi, the son-in-law of Ibn al-'Arabi, and it seems that mysticism, as propagated by Sufi masters of his time, was not appealing to his mind and once the occasion was suitable, he composed his own manual of philosophical Sufism in the form of a small booklet entitled Awsaf al-Ashraf "The Attributes of the Illustrious".

As the armies of Genghis Khan swept his homeland, he fled to join the Ismailis and made his most important contributions in science during this time when he was moving from one stronghold to another. He finally joined Hulagu Khan's ranks, after the invasion of the Alamut castle by the Mongol forces.




He has more than 150 books in Persian language (Farsi) and Arabic language, some of them are:


a)    Kitāb al-Shakl al-qattā Book on the complete quadrilateral. A five volume summary of trigonometry.


b)    Al-Tadhkirah fi'ilm al-hay'ah – A memoir on the science of astronomy. Many commentaries were written about this work called Sharh al-Tadhkirah (A Commentary on al-Tadhkirah) - Commentaries were written by Abd al-Ali ibn Muhammad ibn al-Husayn al-Birjandi and by Nazzam Nishapuri.

  c)    Akhlaq-i-Nasri – A work on ethics.

 d)    al-Risalah al-Asturlabiyah – A Treatise on astrolabe.

  e)    Zij-i ilkhani (Ilkhanic Tables) – A major astronomical treatise, completed in 1272.

 f)       sharh al-isharat (Commentary on Avicenna's Isharat)

  g)    Awsaf al-Ashraf a short mystical-ethical work in Persian

 h)    Tajrid al-Itiqadat (A commentary on Shia doctrines)


 During his stay in Nishapur, Tusi established a reputation as an exceptional scholar. "Al-Tusi’s prose writing, which number over 150 works, represent one of the largest collections by a single Islamic author. Writing in both Arabic and Persian, Nasir al-Din Tusi dealt with both religious (“Islamic”) topics and non-religious or secular subjects (“the ancient sciences”). His works include the definitive Arabic versions of the works of Euclid, Archimedes, Ptolemy, Autolycus, and Theodosius of Bithynia.



Further information: Zij-i Ilkhani and Tusi-couple

Tusi convinced Hulegu Khan to construct an observatory for establishing accurate astronomical tables for better astrological predictions. Beginning in 1259, the Rasad Khaneh observatory was constructed in Azarbaijan, west of Maragheh, the capital of the Ilkhanate Empire.

Based on the observations in this for the time being most advanced observatory, Tusi made very accurate tables of planetary movements as depicted in his book Zij-i ilkhani (Ilkhanic Tables). This book contains astronomical tables for calculating the positions of the planets and the names of the stars. His model for the planetary system is believed to be the most advanced of his time, and was used extensively until the development of the heliocentric model in the time of Nicolaus Copernicus. Between Ptolemy and Copernicus, he is considered by many to be one of the most eminent astronomers of his time, and his work and theory in astronomy can also be compared to that of the Chinese scientist Shen Kuo (1031-1095 AD)

For his planetary models, he invented a geometrical technique called a Tusi-couple, which generates linear motion from the sum of two circular motions. He used this technique to replace Ptolemy's problematic equant and it was later employed in Ibn al-Shatir's geocentric model and Nicolaus Copernicus' heliocentric Copernican model. He also calculated the value for the annual precession of the equinoxes and contributed to the construction and usage of some astronomical instruments including the astrolabe.

 Tūsī criticized Ptolemy's use of observational evidence to show that the Earth was at rest, noting that such proofs were not decisive. Although it doesn't mean that he was a supporter of mobility of the earth, as he and his 16th-century commentator al-Bīrjandī, maintained that the earth's immobility could be demonstrated, but only by physical principles found in natural philosophy. Tusi's criticisms of Ptolemy were similar to the arguments later used by Copernicus in 1543 to defend the Earth's rotation.

 About the real essence of the Milky Way, Tūsī in his Tadhkira writes: "The Milky Way, i.e. the galaxy, is made up of a very large number of small, tightly-clustered stars, which, on account of their concentration and smallness, seem to be cloudy patches. Because of this, it was likened to milk in color." Three centuries later the proof of the Milky Way consisting of many stars came in 1610 when Galileo Galilei used a telescope to study the Milky Way and discovered that it is really composed of a huge number of faint stars.
