Musannaf Ibn Abi Shaybah 27182 — What a man is commanded

Sayyiduna Anas (may Allah be pleased with him) said: I was with the children when the Prophet (peace and blessings be upon him) passed by us, and he (peace and blessings be upon him) greeted us with salam. Then he (peace and blessings be upon him) sent me on an errand and sat down in the shade of a wall until I came back to him (peace and blessings be upon him). I informed him (peace and blessings be upon him) about that errand. Then when I came to Sayyidah Umm Sulaym (may Allah be pleased with her), she said: What kept you back today? I said: The Prophet (peace and blessings be upon him) sent me on an errand. She said: What was the errand? I said: It is a secret of the Messenger of Allah (peace and blessings be upon him). She said: Guard the secret of the Messenger of Allah (peace and blessings be upon him). Sayyiduna Anas (may Allah be pleased with him) said: I did not tell anyone about it.
