On the authority of Hudhaifah Ibn Al-Yamân (may Allah be pleased with him and his father) who reported that the Prophet (peace be upon him) said: “By Allah in whose Hand my soul is, you’d better enjoin what is right and forbid what is wrong or Allah will descend upon you His severe punishment and then you supplicate Him but He will not answer your supplication”

[Narrated by At-Tirmidhi, Hadith no.2169]
