43. Chapter: Honouring the people of the family of the Messenger of Allah and their clear excellence
Allah Almighty said, "Allah wishes to remove all impurity from you, People of the House, and to purify you completely," (33:33)
and the Almighty said, "As for those who honour Allah's sacred rites, that (honour) comes from the taqwa in their hearts." (W22:30; H22:32)
346. Yazid ibn Hayyan said, "Husayn ibn Sabura, 'Amr ibn Muslim and I went to Zayd ibn Arqam . When we were sitting with him, Husayn said to him, 'Zayd, you have received much good. You saw the Messenger of Allah, heard his words, raided with him and prayed behind him. You have received much good, Zayd. Zayd, tell us something you heard from the Messenger of Allah, may Allah bless him and grant him peace.' He said, 'Nephew, I have reached old age and have become old. I have forgotten some of what I used to remember from the Messenger of Allah, may Allah bless him and grant him peace. So accept what I relate to you and do not press me for what I do not.' Then he said, 'The Messenger of Allah, may Allah bless him and grant him peace, stood up among us one day to address us at a watering-place called Khumma between Makka and Madina. He praised and glorified Allah, admonished and reminded people and then said, "O people! I am a mortal and the messenger of my Lord will soon come to me and I will respond. I leave you two great things. The first is the Book of Allah which contains guidance and light. So take the Book of Allah and cling firmly to it." He promoted the Book of Allah and stimulated our desire for it. Then he said, "And the people of my house. I remind you of Allah with respect to the people of my house. I remind you of Allah with respect to the people of my house."' Husayn said to him, 'Who are the people of his house, Zayd? Are not his wives the people of his house?' He said, 'His wives are among the people of his house, but the people of his house are those who were forbidden to take sadaqa after him.' He said, 'Who are they?' He said, 'They are the family of 'Ali, the family of 'Aqil, the family of Ja'far and the family of 'Abbas.' He said, 'All of these were forbidden sadaqa?' He said, 'Yes.'" [Muslim]
In one variant, "I leave among you two great things. One of them is the Book of Allah and it is the rope of Allah. All who follow it are guided. All who abandon it are misguided."
347. Ibn 'Umar reported that Abu Bakr as-Siddiq said, "Respect Muhammad, may Allah bless him and grant him peace, in the members of his family." [al-Bukhari]
