Surah An-Nisaa, Verse 140
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
Translation — Sahih International
And it has already come down to you in the Book that when you hear the verses of Allah [recited], they are denied [by them] and ridiculed; so do not sit with them until they enter into another conversation. Indeed, you would then be like them. Indeed Allah will gather the hypocrites and disbelievers in Hell all together -
