Will you please tell me the periods in which Imam Abu Hanifa, Imam Malik, Imam Shafi'e and Imam Ahmed existed?
Praise be to Allah, the Lord of the Worlds; and may His blessings and peace be upon our Prophet Muhammad and upon all his Family and Companions. Here is the brief information about the four Imams: 1) Abu Hanifa al-Nu`aman bin Thabit al-Kufi was a great scholar and founder of the Hanafi school of thought. He narrated from Nafi`e , Ataa and others. Abu Yousaf , Muhammad bin al-Hasan (his known students) and others reported from him. He was born in 80 A.H and died 150 A.H. 2) Abu Abdullah Malik bin Anas al-Asbahi . He was an Imam and Muhaddith, and also the Imam of al-Madinah. He reported knowledge from many of the Tabi'een.

He made many long journeys to collect knowledge of Islam. He is one of the students of Imam Malik . The Shafi'e school of thought is ascribed to him. He died 204 A.H. 4) Ahmad bin Hanbal , Abu Abdullah al-Shaibani was born in 164 A.H. in Baghdad.
