200 FAQ On Muslims Belief by Hafiz Ibn Ahmed Al Hakami

A--- Allah the Almighty says: {Let there arise out of you a group of people inviting to all that is good (Islam), enjoining Al-Ma'ruf (i.e.

Islamic Monotheism and all that Islam orders one to do) and forbidding Al-Munkar (polytheism and disbelief and all that Islam has forbidden). And it is they who are the successful}. (Al 'Imran, 104)

Abu Sa'id Al-Khudri (May Allah be pleased with him) narrated, I heard the Messenger of Allah (Peace be upon him) as saying: "He who amongst you sees something abominable should modify it with the help of his hand; and if he has not strength enough to do it, then he should do it with his tongue, and if he has not strength enough to do it, (even) then he should (abhor it) from his heart, and that is the least of faith. " (Sahih Muslim)

There are countless proofs and evidences pertaining to this issue, all of which implies the necessity of enjoining the good and forbidding the evil on whosoever sees it. If anyone carries this out, the rest of the Ummah will be saved from Allah's Wrath. The more one is able (to do it) and knowledgeable, the more it is necessary for him to do it himself. Verily, none was saved upon the descending of torment on the heads of the disobedient but those who forbade them from committing the evil.
