سنن أبي داود

Narrated Kaladah ibn Hanbal:

Safwan ibn Umayyah sent him with some milk, a young gazelle and some small cucumbers to the Messenger of Allah (ﷺ) when he was in the upper part of Mecca. I entered but I did not give a salutation. He said: Go back and say: "Peace be upon you"! This happened after Safwan ibn Umayyah and embraced Islam. Amr said: Ibn Safwan told me all this on the authority of Kaladah ibn Hanbal, and he did not say: I heard it from him.

Abu Dawud said: Yahya b. Habib said: Umayyah b. Safwan. He did not say: I heard from Kaladah b. Hanbal. Yahya also said: 'Amr b. 'Abd Allah b. Safwan told him that Kaladah b. al-Hanbal told him.
