Allah never sent any prophet nor did He invest anyone with authority except that he has two entourages: one entourage enjoins him to do good and encourages him to carry it out; another entourage enjoins him to do evil and incites him to carry it out.

Abu Sa‘īd al-Khudri and Abu Hurayrah (may Allah be pleased with both of them) reported that the Prophet (may Allah's peace and blessings be upon him) said: "Allah never sent any prophet nor did He invest anyone with authority except that he has two entourages: one entourage enjoins him to do good and encourages him to carry it out; another entourage enjoins him to do evil and incites him to carry it out. Saved is the one whom Allah protects.''
