Musnad Abi Ya'la 3323 — when the Messenger of Allah ﷺ made peace

It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that when the Messenger of Allah (peace and blessings be upon him) made peace with Quraysh on the day of al-Hudaybiyah, he said to Sayyiduna Ali (may Allah be pleased with him): "Write: Bismillahir-Rahmanir-Rahim (In the name of Allah, the Most Gracious, the Most Merciful)." Suhayl bin Amr (may Allah be pleased with him) (who was at that time the representative of the polytheists) said: We do not know al-Rahman al-Rahim; rather, write: 'Bismika Allahumma (In Your name, O Allah).' Then the Messenger of Allah (peace and blessings be upon him) said to Sayyiduna Ali (may Allah be pleased with him): "Write: These are the terms on which Muhammad, the Messenger of Allah (peace and blessings be upon him), has made peace." Suhayl bin Amr said: If we knew that you are the Messenger of Allah, we would follow you and not deny you; rather, write your name and your father's name. Then the Prophet (peace and blessings be upon him) said to Sayyiduna Ali (may Allah be pleased with him): "Write: Muhammad bin Abdullah." Then it was agreed: "Whoever of you comes to us (without permission), we will return him to you, and whoever of us goes to you, you will keep him with you." The Companions (may Allah be pleased with them) said (in concern): O Messenger of Allah (peace and blessings be upon him), are you giving them this concession? He (peace and blessings be upon him) said: "Yes, because whoever of us goes over to them, may Allah keep him far (from His mercy); and whoever of them comes to us and we return him to them (in keeping the treaty), Allah Almighty will soon make for him some relief and a way out."
