The children of the Prophet Muhammad ﷺ

The Prophet ﷺ went out one morning wearing a cloak of black hair with a pattern on it. Al-Hasan ibn Ali came and he brought him in (under the cloak); then al-Husayn came and went in with him; then Fatima came and he brought her in; then Ali came and he brought him in. Then he said: "Allah only wishes to remove impurity from you, O people of the House, and to purify you thoroughly."
