I heard Ka`b bin Malik narrating (when he did not join the battle of Tabuk): Allah's Messenger (ﷺ) forbade all the Muslims to speak to us. I would come to Allah's Messenger (ﷺ) and greet him, and I would wonder whether the Prophet (ﷺ) did move his lips to return to my greetings or not till fifty nights passed away. The Prophet (ﷺ) then announced (to the people) Allah's forgiveness for us (acceptance of our repentance) at the time when he had offered the Fajr (morning) prayer.
Sahih al-Bukhari Book 79, Hadith 29
← Previous Hadith Usama bin Zaid said, "The Prophet (ﷺ) rode over a donkey with a saddle underneath which there was a thick soft Fadakiya velvet sheet. Usama bin Zaid was his companion rider, and he was going to pay a visit to Sa`d bin Ubada (who was sick) at the dwelling place of Bani Al-Harith bin Al-Khazraj, and this incident happened before the battle of Badr. The Prophet (ﷺ) passed by a gathering in which there were Muslims and pagan idolators and Jews, and among them there was `Abdullah bin Ubai bin Salul, and there was `Abdullah bin Rawaha too. When a cloud of dust raised by the animal covered that gathering, `Abdullah bin Ubai covered his nose with his Rida (sheet) and said (to the Prophet), "Don't cover us with dust." The Prophet (ﷺ) greeted them and then stopped, dismounted and invited them to Allah (i.e., to embrace Islam) and also recited to them the Holy Qur'an. `Abdullah bin Ubai' bin Salul said, "O man! There is nothing better than what you say, if what you say is the truth. So do not trouble us in our gatherings. Go back to your mount (or house,) and if anyone of us comes to you, tell (your tales) to him." On that `Abdullah bin Rawaha said, "(O Allah's Messenger (ﷺ)!) Come to us and bring it(what you want to say) in our gatherings, for we love that." So the Muslims, the pagans and the Jews started quarreling till they were about to fight and clash with one another. The Prophet (ﷺ) kept on quietening them (till they all became quiet). He then rode his animal, and proceeded till he entered upon Sa`d bin 'Ubada, he said, "O Sa`d, didn't you hear what Abu Habbab said? (He meant `Abdullah bin Ubai). He said so-and-so." Sa`d bin 'Ubada said, "O Allah's Messenger (ﷺ)! Excuse and forgive him, for by Allah, Allah has given you what He has given you. The people of this town decided to crown him (as their chief) and make him their king. But when Allah prevented that with the Truth which He had given you, it choked him, and that was what made him behave in the way you saw him behaving." So the Prophet excused him.

Sahih al-Bukhari Book 79, Hadith 28 Next Hadith → A group of Jews came to Allah's Messenger (ﷺ) and said, "As-samu 'Alaika " (Death be on you), and I understood it and said to them, "Alaikum AsSamu wa-l-la'na (Death and curse be on you)." Allah's Apostle said, "Be calm! O `Aisha, for Allah loves that one should be kind and lenient in all matters." I said. "O Allah's Messenger (ﷺ)! Haven't you heard what they have said?" Allah's Messenger (ﷺ) said, "I have (already) said (to them), 'Alaikum (upon you).' "
