Musannaf Ibn Abi Shaybah 12167 — Those who permitted visiting graves

Sulayman bin Buraydah narrates from his father (may Allah be pleased with him) that when the Prophet (peace and blessings be upon him) conquered Makkah, he (peace and blessings be upon him) came to an old grave and sat down beside it, and he became like one who is addressing someone, and the people sat around him. When he (peace and blessings be upon him) stood up, he (peace and blessings be upon him) was weeping. Sayyiduna Umar (may Allah be pleased with him) met him (peace and blessings be upon him), and Umar was the boldest of the people towards him. Sayyiduna Umar said: "O Messenger of Allah! May my father and mother be sacrificed for you (peace and blessings be upon him), what has made you (peace and blessings be upon him) weep?" He (peace and blessings be upon him) said: "This is the grave of my honoured mother. I asked my Lord for permission to visit it, and I was given permission; and I asked for permission to seek forgiveness for her, and it was not given to me. I remembered her, my heart was moved with tenderness, and I wept." The narrator says: The Prophet (peace and blessings be upon him) was never seen weeping more than he wept that day.
