[Abu Hafsat]

As-Salaam alaikum,




 Sayyadina Abdullah Ibn Mas'ud, may Allah be pleased with him, narrated that the Prophet, Sallallahu alaihi Wasallam, said:--




     "I am the city of knowledge, Abu Bakr is its foundation, Umar is its wall,




    Usman is its roof and Ali is its portal [gate]."  [Musnad-ul-Firdau, vol. 1 Hadith No. 105].
