*Hakim Abu Ali Sina* 
Avicenna is a physician, mathematician, physicist, astronomer, geologist, geographer, poet, logician, philosopher, musician and statesman of the fourth and fifth centuries of the Islamic calendar.
Avicenna was born in the city of Khor Musa, a province of Bukhara. He began his education as a teenager and soon became one of the physicians of the court of Amir Noah Samani. With the political situation in Khorezm becoming unstable, he was forced to migrate from city to city because Mahmud Ghaznavi was looking for court scientists, especially Avicenna. Avicenna, heir to the unfavorable conditions of his era, was forced to write many of his works on horseback. He has many works in the fields of philosophy, logic, physics and medical science.
Avicenna is one of the most influential figures not only in the Islamic world but also in the world. His two books, Shifa and Qanun, were the most widely published in Europe during the Renaissance and until the 16th century (the number of printed copies of these books exceeded the number of Bibles).
Ibn Sina also reformed the "Millen theory" in physics and established the "New Sinaean Plan" in logic. In the field of philosophy, he tried to reconcile Masha'i philosophy with religion. 
At the end of his life, Ibn Sina was the minister of the government of Ala'ad al-Dawlah in Hamadan and later the minister of the government of Al-Kakuyeh in Isfahan. Although his tomb is located in Hamadan, this possibility is also true for the tomb in Isfahan. (It should be added that in Ibn Sina's time, a sage was referred to as an omniscient scientist, which not everyone was able to achieve).
