Umm Salama added: "I was in my room performing prayers when the Arch-Angel Gabriel revealed: "O Allah, these are my Family and Kin; therefore, remove all abomination from them and make them pure and spotless." Upon hearing that, I looked in the house, and said: "Am I one of them, O Apostle of Allah?' Moreover, Tirmadhi reported in his "Sahih" that Allah's Messenger since the time this verse was revealed, and for six months thereafter, stood by Fatima’s (sa) house (door), and said: "(Time for) prayers Ahlul-Bayt; Allah only wished to remove all abomination from you and make you pure and spotless." Ibn Sabagh al-Maliki in his book al-Fosoul al-Muhemah p.7, narrated a tradition similar to the one already mentioned by Wahidi; but he added: Some poets said the following in this regard: Surely Muhammad and his successor, and Their two sons, and his virtuous, and pure daughter Are the people of the cloak who in adhering to them, I long for peace and success on the Last Day.
Abu Bakr Suyuti narrated this tradition on the authority of Umm Salama, Aisha, Abu Sa'id Al-Khudari, Zeid Ibn Arqam, Ibn Abbas, Dahak Ibn Muzahim, Abu al-Hamra, Omar Ibn Salama and others in his books: al-Durr al-Manthur v. 5, p. 198, Al-Khasaes al-Kubra v. 2, p. 264, and Al-Itqan v. 2, p. 200. They all reported that the Prophet (S) gathered Fatima, ‘Ali, Al-Hasan and Al-Husayn (as), when the verse 'And, Allah only wishes to remove... ", and covered them with a cloak.
He then said: "By Allah, these are my Ahlul-Bayt, therefore remove all abomination from them pure and spotless." Tabari in Dhakhaer al-Uqbi p. 21, declared that this verse was revealed in regard to the purified five (the Prophet, ‘Ali, Fatima, Hasan, Husayn), relying on Omar Ibn Abu Salama's narration.
