Musannaf Ibn Abi Shayba 36:307

Abu Usama narrated to us, from Zakariya, from Abu Ishaq, from al-Bara’ who said: When the Messenger of Allah (ﷺ) was prevented from reaching the House (the Kaaba), the people of Mecca made a peace treaty with him on the condition that he enter it and stay in it for three days, and that he not enter it except with the sheath of the weapon—the sword and its scabbard—and that he not take anyone out with him from its people, and that he not prevent anyone who was with him from staying in it. He said to Ali: "Write the terms between us: In the name of Allah, the Most Gracious, the Most Merciful. This is what Muhammad, the Messenger of Allah, has agreed upon." The polytheists said: "If we knew that you were the Messenger of Allah, we would have followed you. But write: Muhammad ibn Abdullah." He said, so he ordered Ali to erase it. Ali said: "No, by Allah, I will not erase it." The Messenger of Allah (ﷺ) said: "Show me its place." So he showed him its place, and he erased it and wrote "ibn Abdullah." He stayed in it for three days. When the third day arrived, they said to Ali: "This is the last day of your companion's condition, so tell him to leave." He informed him of that, and he said: "Yes," and he left.
