It was narrated that Abu Ayyub said: “I heard the Messenger of Allah صلی اللہ علیہ وآلہ وسلم say: ‘No Prophet صلی اللہ علیہ وآلہ وسلم has ever been sent, nor has there been any KhalIfah after him, but he has two groups of advisers, a group that tells him to do good and a group that tells him to do evil. Whoever is protected from the evil groUP then he is indeed protected.” (Sahih)
