This Madh-hab was named after al-Layth ibn Sa’d who was born in Egypt of Persian parentage in the year 716 CE. After an extensive study of all the then known areas of Islamic learning, alLayth became the major scholar of Egypt. He was contemporary of both Imaam Abu Haneeah and Imm Maalik. In fact he carried on a debate with Imaam Maalik by mail on various points of Islamic law, one of which was Maalik’s inclusion of Madeenite custom as an independent source of Islamic law.

Imaam al-Layth’s Madh-hab disappeared shortly after his death in 791 CE for the following reasons:

(a) He neither, compiled, dictated, nor instructed his followers to record his legal opinions and their proofs according to his interpretations of the Qur’aan, Sunnah and legal positions of the Sahaabah. Thus, very little remains of his Mdh-hab beyond a few references in the early books of comparative Fiqh.

(b) The number of students under al-Layth was small and since none of them became outstanding jurists, they were not in an influential position to popularize his Madh-hab.

(c) Ash-Shaafi’ee, one of the most outstanding Fiqh scholars, settled in Egypt Immediately after al-Layth’s death and his Madh-hab quickly displaced of al-Layth.

It is interesting to note that Imaam ash-Shaafi’ee who had studied extensively under Maalik and under al-Layth’s students was reported to have observed that al-Layth was a greater jurist than Maalik, but his students neglected him.141
