Narrated Usama bin Zaid:

Allah's Messenger (ﷺ) rode a donkey, equipped with a thick cloth-covering made in Fadak and was riding behind him. He was going to pay visit to Sa`d bin Ubada in Banu Al-Harith bin Al-Khazraj; and this incident happened before the battle of Badr. The Prophet (ﷺ) passed by a gathering in which `Abdullah bin Ubai bin Salul was present, and that was before `Abdullah bin Ubai embraced Islam. Behold in that gathering there were people of different religions: there were Muslims, pagans, idol-worshippers and Jews, and in that gathering `Abdullah bin Rawaha was also present. When a cloud of dust raised by the donkey reached that gathering, `Abdullah bin Ubai covered his nose with his garment and then said, "Do not cover us with dust." Then Allah's Messenger (ﷺ) greeted them and stopped and dismounted and invited them to Allah (i.e. to embrace Islam) and recited to them the Holy Qur'an. On that, `Abdullah bin Ubai bin Saluil said, "O man ! There is nothing better than that what you say. If it is the truth, then do not trouble us with it in our gatherings. Return to your mount (or residence) and if somebody comes to you, relate (your tales) to him." On that `Abdullah bin Rawaha said, "Yes, O Allah's Apostle! Bring it (i.e. what you want to say) to us in our gathering, for we love that." So the Muslims, the pagans and the Jews started abusing one another till they were on the point of fighting with one another. The Prophet (ﷺ) kept on quietening them till they became quiet, whereupon the Prophet rode his animal (mount) and proceeded till he entered upon Sa`d bin Ubada. The Prophet (ﷺ) said to Sa`d, "Did you not hear what 'Abu Hub-b said?" He meant `Abdullah bin Ubai. "He said so-andso." On that Sa`d bin Ubada said, "O Allah's Messenger! Excuse and forgive him, for by Him Who revealed the Book to you, Allah brought the Truth which was sent to you at the time when the people of this town (i.e. Medina) had decided unanimously to crown him and tie a turban on his head (electing him as chief). But when Allah opposed that (decision) through the Truth which Allah gave to you, he (i.e. `Abdullah bin Ubai) was grieved with jealously. and that caused him to do what you have seen." So Allah's Messenger (ﷺ) excused him, for the Prophet (ﷺ) and his companions used to forgive the pagans and the people of Scripture as Allah had ordered them, and they used to put up with their mischief with patience. Allah said: "And you shall certainly hear much that will grieve you from those who received the Scripture before you and from the pagans........'(3.186) And Allah also said:--"Many of the people of the Scripture wish if they could turn you away as disbelievers after you have believed, from selfish envy.." (2.109) So the Prophet (ﷺ) used to stick to the principle of forgiveness for them as long as Allah ordered him to do so till Allah permitted fighting them. So when Allah's Messenger (ﷺ) fought the battle of Badr and Allah killed the nobles of Quraish infidels through him, Ibn Ubai bin Salul and the pagans and idolaters who were with him, said, "This matter (i.e. Islam) has appeared (i.e. became victorious)." So they gave the pledge of allegiance (for embracing Islam) to Allah's Messenger (ﷺ) and became Muslims.

Narrated Usama bin Zaid:

That Allah's Messenger (ﷺ) rode over a donkey covered with a Fadakiya (velvet sheet) and Usama was riding behind him. He was visiting Sa`d bin 'Ubada (who was sick) in the dwelling place of Bani Al-Harith bin Al-Khazraj and this incident happened before the battle of Badr. They proceeded till they passed by a gathering in which `Abdullah bin Ubai bin Salul was present., and that was before `Abdullah bin Ubat embraced Islam. In that gathering there were Muslims, pagan idolators and Jews, and among the Muslims there was `Abdullah bin Rawaha. When a cloud of dust raised by (the movement of ) the animal covered that gathering, `Abdullah bin Ubai covered his nose with his garment and said, "Do not cover us with dust." Allah's Messenger (ﷺ) greeted them, stopped, dismounted and invited them to Allah (i.e. to embrace Islam) and recited to them the Holy Qur'an. On that `Abdullah bin Ubai bin Salul said to him, "O man! There is nothing better than what you say, if it is the truth. So do not trouble us with it in our gatherings, but if somebody comes to you, you can preach to him." On that `Abdullah bin Rawaha said "Yes, O Allah's Messenger! Call on us in our gathering, for we love that." So the Muslims, the pagans and the Jews started abusing one another till they were about to fight with one another. Allah's Messenger (ﷺ) kept on quietening them till all of them became quiet, and then Allah's Messenger (ﷺ) rode his animal and proceeded till he entered upon Sa`d bin 'Ubada. Allah's Messenger (ﷺ) said, "O Sa`d! Didn't you hear what Abu Habab said?" (meaning `Abdullah bin Unbar). "He said so-and-so." Sa`d bin Ubada said, "O Allah's Messenger! Let my father be sacrificed for you ! Excuse and forgive him for, by Him Who revealed to you the Book, Allah sent the Truth which was revealed to you at the time when the people of this town had decided to crown him (`Abdullah bin Ubai) as their ruler. So when Allah had prevented that with the Truth He had given you, he was choked by that, and that caused him to behave in such an impolite manner which you had noticed." So Allah's Messenger (ﷺ) excused him. (It was the custom of) Allah's Messenger (ﷺ) and his companions to excuse the pagans and the people of the scripture (Christians and Jews) as Allah ordered them, and they used to be patient when annoyed (by them). Allah said: 'You shall certainly hear much that will grieve you from those who received the Scripture before you.....and from the pagans (3.186) He also said: 'Many of the people of the scripture wish that if they could turn you away as disbelievers after you have believed. .... (2.109) So Allah's Messenger (ﷺ) used to apply what Allah had ordered him by excusing them till he was allowed to fight against them. When Allah's Messenger (ﷺ) had fought the battle of Badr and Allah killed whomever He killed among the chiefs of the infidels and the nobles of Quraish, and Allah's Messenger (ﷺ) and his companions had returned with victory and booty, bringing with them some of the chiefs of the infidels and the nobles of the Quraish as captives. `Abdullah bin Ubai bin Salul and the pagan idolators who were with him, said, "This matter (Islam) has now brought out its face (triumphed), so give Allah's Messenger (ﷺ) the pledge of allegiance (for embracing Islam.)". Then they became Muslims.
