Ebu’l-Hasan al-Velvaleci, a famous Islamic scholar narrated “I went to visit Abu Reyhan al-Biruni. He was lying in his deathbed, and hardly breathing. Then he said to me,
“One day you mentioned an equation about the calculation of the rights of the grandma in the inheritance, how was it?” With a little gush I said, “Do you still ask me these things even in this situation? He said, “Is it better if I leave this world knowing this matter, or say farewell without knowing?”
Therefore, I told him the matter again. He listened and memorized. Then, he told me about the things he was going to do. I left after a while. Not long after I had left, I heard loud crying and shouting. When I looked back, Abu Rayhan al-Biruni had passed away.
Abu Rayhan Muhammad (Ahmed al-Biruni) who dedicated his life to knowledge and learning the things he didn’t know was born in Kas, which was the center of Harezm region on 3 Dhu al-Hijjah 362 (h) / September, 4, 973 (c). There is no information about Biruni’s family. Once he mentioned that he did not know about his grandfather and his family in one of his poems. He also stated that he did not even know his father.
Islamic scholar al-Biruni, who enlightened the scientific world with his pioneer discoveries and inventions, is an important Turkish-Islamic figure, whose precious works take place in fields such as astronomy, pharmacology, mathematics, physics, medicine, geography, history, and so on. He died on December 13, 1048.
