Hadith: Hudhaifah ibn Yaman Radiyallahu 'anhu narrates that Nabi
Sallallahu 'alaihi wasallam said: By Him, in Whose Hand is my life,
undoubtedly you must enjoin what is good and forbid what is evil or else
Allah will certainty send upon you a Punishment; then you will
supplicate to him and He will not accept it. (Tirmidhi: 2169)
