Sayyidah Umm Salamah (may Allah be pleased with her) said: The Messenger of Allah (peace and blessings be upon him) said to me: "Sit at the door, and let no one come in to me." So I stood at the door, and then Husayn (may Allah be pleased with him) came. I went to stop him, but the boy got ahead of me and went in to his grandfather. I said: O Prophet of Allah! May Allah make me your ransom! You ordered me not to let anyone come in to you, and this son of yours came; I tried to stop him, but he got ahead of me. When it went on for a long time, I peeped through the door and saw you turning something over in your palms, with your tears flowing, and the boy (sitting) on your stomach. He (peace and blessings be upon him) said: "Yes, Jibril came to me and informed me that my Ummah will kill him, and he brought me the soil on which he will be killed; this is the soil I am turning over in my palms."
