أَئِنَّكُمْ لَتَأْتُونَ ٱلرِّجَالَ وَتَقْطَعُونَ ٱلسَّبِيلَ وَتَأْتُونَ فِى نَادِيكُمُ ٱلْمُنكَرَ ۖ فَمَا كَانَ جَوَابَ قَوْمِهِۦٓ إِلَّآ أَن قَالُوا۟ ٱئْتِنَا بِعَذَابِ ٱللَّهِ إِن كُنتَ مِنَ ٱلصَّٰدِقِينَ
For come ye not in unto males, and cut ye not the road (for travellers), and commit ye not abomination in your meetings? But the answer of his folk was only that they said: Bring Allah's doom upon us if thou art a truthteller!
