Musannaf Ibn Abi Shaybah 39619 — The Hudaybiyah campaign

Sayyiduna Jabir (may Allah be pleased with him) states: On the day of al-Hudaybiyah we numbered fourteen hundred. He (peace and blessings be upon him) said to us: "This day you are the best of the people of the earth."
It is narrated from Sayyiduna al-Miswar (may Allah be pleased with him) and Marwan that the Messenger of Allah (peace and blessings be upon him) set out in the year of al-Hudaybiyah with ten-odd hundred of his (peace and blessings be upon him) Companions. When he (peace and blessings be upon him) was at Dhu al-Hulayfah, he (peace and blessings be upon him) garlanded and marked the sacrificial animals and entered the state of ihram.
