Enjoin Good; Forbid Evil

السلام عليكم

بِسْمِ اللهِ الرَّحْمنِ الرَّحِيمِ

By Him, in Whose Hand is my life, undoubtedly you must enjoin what is good and forbid what is evil or else Allah will certainly send upon you a Punishment;then you will supplicate to him and He will not accept it.

[Tirmidhi]
