Umm Salama bint Abu Umaya reported,
The Prophet ﷺ wrapped a cloak around Hasan, Husayn, Ali, and Fatimah, and then said, "Allah, these are the people of my household and those closest to me. Remove impurity from them and purify them thoroughly."Umm Salama asked, "And am I with them, Messenger of Allah?"He replied, "You are upon goodness."
