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."

It is narrated from Amr bin Dinar (may Allah have mercy on him) that Sayyiduna Ibn Abbas (may Allah be pleased with them both) recited the verse of the Noble Qur'an: «﴿وَشَاوِرْهُمْ فِي الْأَمْرِ﴾» [آل عمران: 159] as «وَشَاوِرْهُمْ فِي بَعْضِ الْأَمْرِ» .

It is narrated from Imam Hasan al-Basri, may Allah have mercy on him, that he said: When a people consult each other in a matter, they are surely guided to the best course of action. Then he recited this verse: «﴿وَأَمْرُهُمْ شُورَىٰ بَيْنَهُمْ﴾» [الشورى: 38] "And their affairs are (decided) by mutual consultation among them."

It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Prophet (peace and blessings of Allah be upon him) said: "Whoever attributes to me something which I have not said, let him take his place in the Fire," "and whoever is consulted by his Muslim brother and gives him wrong advice, he has betrayed the one who consulted him," "and whoever gives a wrong fatwa without knowledge (and the one who asked acts upon it), then its sin will be upon the one who gave the fatwa."
