Urwah (may Allah have mercy on him) said: Abu Hudhayfah bin al-Yaman (the father of Hudhayfah) was a very old man, and on the day of Uhud he was lifted up into the fortresses along with the women. He went out seeking martyrdom and came from the direction of the polytheists, so the Muslims rushed at him and their swords fell upon him, while Hudhayfah was saying: "My father! My father!" But they did not hear him because of the preoccupation of battle, until they killed him. Hudhayfah said: "May Allah forgive you, and He is the Most Merciful of those who show mercy." So the Prophet (peace and blessings be upon him) ruled that blood money be paid for him.
