Quran 4:140 An-Nisa, ayah 140 of 176

وَقَدْ نَزَّلَ عَلَيْكُمْ فِى ٱلْكِتَـٰبِ أَنْ إِذَا سَمِعْتُمْ ءَايَـٰتِ ٱللَّهِ يُكْفَرُ بِهَا وَيُسْتَهْزَأُ بِهَا فَلَا تَقْعُدُوا۟ مَعَهُمْ حَتَّىٰ يَخُوضُوا۟ فِى حَدِيثٍ غَيْرِهِۦٓ ۚ إِنَّكُمْ إِذًا مِّثْلُهُمْ ۗ إِنَّ ٱللَّهَ جَامِعُ ٱلْمُنَـٰفِقِينَ وَٱلْكَـٰفِرِينَ فِى جَهَنَّمَ جَمِيعًا ۝١٤٠

4:140 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;
