It is said that Imam Malik sought out over three hundred Sahaba (those who saw the Companions of the Holy Prophet). From them he acquired the knowledge of the Holy Prophet's sayings, Hadith, (plural ahadith) - and the Holy Prophet's Deeds, - Sunnah. Imam Malik studied Fiqh under the guidance of nearly one hundred learned Shaikhs who were residing in the city of the Prophet at the time. Among Imam Maliks writings is the great work entitled Kitab-al-Muwatta, which is the earliest surviving book(s) of Islamic law and Hadith.
