Kitab ul Athar by Imam Muhammad Bin Hasan Al-Shaybani
Imam Muhammad ibn al-Hasan al-Shaybani (132 – 189), who was one of the foremost students of Imam Abu Hanifah, and an undisputed authority in fiqh (jurispudence) and lughah (language), was also a hafiz (memoriser of a large number) of hadith as mentioned by al-Daraqutni and as is apparent from his works on hadith like his Muwatta’, Kitab al-Athar and Kitab al-Hujjah, all of which are in print. His reliability in hadith was transmitted from ‘Ali ibn al-Madini (d. 235) and al-Daraqutni (d. 385).
Another version of the book 'Kitab ul Athar' is attributed to Imam Abu Yusuf. We have provided both of these books here.
Imam Abu Yusuf and Imam Muhammad Bin Hasan Al-Shaybani were both the students of Imam Abu Hanifa, May Allah be pleased with them all.
