Musannaf Ibn Abi Shaybah

Hazrat Aisha (may Allah be pleased with her) narrates that the Noble Prophet (peace and blessings be upon him) went out in the morning while he was wearing a black cloak on which there were pictures of camel saddles. Then Hazrat Hasan (may Allah be pleased with him) came, and the Prophet (peace be upon him) included him in the cloak. Then Hazrat Husain (may Allah have mercy on him) came, and the Prophet (peace be upon him) included him in the cloak as well. Then Hazrat Fatimah (may Allah be pleased with her) came, and the Prophet (peace be upon him) included her in the cloak as well. Then Hazrat Ali (may Allah be pleased with him) came, and the Prophet (peace be upon him) included him in the cloak as well. Then the Prophet (peace be upon him) recited this verse: Translation: Allah only wishes to remove impurity from you, O people of the house (of the Prophet ﷺ), and to purify you completely.
