Aisha reported that
Allah's Messenger ﷺ went out one morning wearing a striped cloak of the black camel's hair that there came Hasan bin Ali, he wrapped him under it. Then came Husain, and he wrapped him under it along with the other one (Hasan). Then came Fatima, and he took her under it. Then came Ali, and he also took him under it and then said:
"Allah only desires to remove the impurity from you, O people of the House. And to purify you with a thorough purification."
Sahih Muslim
Book 31 Hadith 5955
