al-Layth ibn Sad

Al-Layth ibn Sad (713-791 CE) was the foremost scholar of Egypt in the second Islamic century and was regarded by many as the equal or even the superior of Imam Malik in jurisprudence. Imam ash-Shafii himself said, 'Al-Layth was more learned in fiqh than Malik, but his companions did not serve him well,' meaning his students failed to systematically record and transmit his legal opinions as Malik's students had done.

Al-Layth was born in Qarqashandah, a village near Fustat (old Cairo), to a family of Persian origin. He traveled widely to study hadith, learning from scholars in Mecca, Medina, and across the Muslim world. He was unique among major scholars in that he combined deep religious scholarship with immense personal wealth, earning reportedly eighty thousand dinars annually from his agricultural lands and trade. Yet he was legendarily generous, giving away his entire income in charity every year. When Imam Malik once sent him a gift of dates, al-Layth returned it with a caravan loaded with gifts worth many times more.

Al-Layth served as the unofficial chief scholar and judge of Egypt, and his legal opinions shaped the religious life of the region for decades. He authored numerous works on hadith and fiqh, though most have not survived. The Maliki and later the Shafii schools eventually replaced his school in Egypt, not because of any weakness in his scholarship but because his students did not codify his teachings with the same rigor. He died in Cairo in 175 AH (791 CE).
