Omar Khayyam and Islam

The philosophy of Omar Khayyam was quite different from official Islamic dogmas. He agreed with the existence of God but objected to the notion that every particular event and phenomenon was the result of divine intervention. Instead he supported the view that laws of nature explained all particular phenomena of observed life. Religious officials asked him many times to explain his different views about Islam. Khayyam eventually made a hajj [pilgrimage] to Mecca in order to prove he was a faithful follower of the religion.
