It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Prophet (peace and blessings of Allah be upon him) asked Sayyiduna Abu Al-Haitham (may Allah be pleased with him): "Do you have a servant?" He replied: "No!" The Prophet (peace be upon him) said: "When captives come to us, come (to me)." Only two captives came to the Prophet (peace be upon him), so Sayyiduna Abu Al-Haitham (may Allah be pleased with him) presented himself. The Prophet (peace be upon him) said: "Take one of them." He said: "O Messenger of Allah! Give me whichever you prefer for me." Then the Prophet (peace be upon him) said: "One who is consulted should act with trustworthiness. Take this one, for I have seen him performing prayer, and I advise you to treat him well." His wife said: "You cannot fulfill what the Prophet (peace be upon him) has advised regarding him except by freeing him." Sayyiduna Abu Al-Haitham (may Allah be pleased with him) said: "He is free." The Messenger of Allah (peace be upon him) said: "Allah has not sent any Prophet nor appointed anyone as a successor except that He appointed for him two confidants: one confidant whose task is to command him to do good and forbid him from evil, and another confidant who does not fall short in leading him to ruin. And whoever is protected from the evil confidant has indeed been protected from evil."
