وَقَدْ نَزَّلَ عَلَيْكُمْ فِى ٱلْكِتَٰبِ أَنْ إِذَا سَمِعْتُمْ ءَايَٰتِ ٱللَّهِ يُكْفَرُ بِهَا وَيُسْتَهْزَأُ بِهَا فَلَا تَقْعُدُوا۟ مَعَهُمْ حَتَّىٰ يَخُوضُوا۟ فِى حَدِيثٍ غَيْرِهِۦٓ ۚ إِنَّكُمْ إِذًۭا مِّثْلُهُمْ ۗ إِنَّ ٱللَّهَ جَامِعُ ٱلْمُنَٰفِقِينَ وَٱلْكَٰفِرِينَ فِى جَهَنَّمَ جَمِيعًا
He hath already revealed unto you in the Scripture that, when ye hear the revelations of Allah rejected and derided, (ye) sit not with them (who disbelieve and mock) until they engage in some other conversation. Lo! in that case (if ye stayed) ye would be like unto them. Lo! Allah will gather hypocrites and disbelievers, all together, into hell;
Surah An-Nisaa(4:140)
Sahih al-Bukhari
Asking Permission
Chapter: Greeting a mix-up gathering
Narrated `Urwa-bin Az-Zubair:
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.
