Musannaf Ibn Abi Shaybah 39618 — The Hudaybiyah campaign

It is narrated from Sayyiduna Anas (may Allah be pleased with him) that Quraysh made peace with the Prophet (peace and blessings be upon him), and among them (those making peace) was Suhayl bin Amr. The Prophet (peace and blessings be upon him) said to Sayyiduna Ali (may Allah be pleased with him): "Write: Bismillah ir-Rahman ir-Rahim (In the name of Allah, the Most Gracious, the Most Merciful)." Suhayl said: "We do not know this Bismillah ir-Rahman ir-Rahim. What is Bismillah ir-Rahman ir-Rahim? Rather write what we know: Bismika Allahumma (In Your name, O Allah)." Then he (peace and blessings be upon him) said: "Write: From Muhammad, the Messenger of Allah." They said: "If we accepted you as the Messenger of Allah, we would simply follow you. Rather write your name and your father's name." At this the Prophet (peace and blessings be upon him) said: "Write: From Muhammad bin Abdullah." Then the polytheists of Quraysh imposed this condition on him (peace and blessings be upon him): that whoever of you comes (to us), we will not return him to you, and whoever of us comes to you, you will return him to us. The Companions said: "O Messenger of Allah (peace and blessings be upon him), will this also be written?" He (peace and blessings be upon him) said: "Yes! Whoever of us goes to them, Allah will put him far away; and whoever of them comes to us, Allah Almighty will make for him a way and an exit."
