قَالُوا۟ يَٰلُوطُ إِنَّا رُسُلُ رَبِّكَ لَن يَصِلُوٓا۟ إِلَيْكَ ۖ فَأَسْرِ بِأَهْلِكَ بِقِطْعٍۢ مِّنَ ٱلَّيْلِ وَلَا يَلْتَفِتْ مِنكُمْ أَحَدٌ إِلَّا ٱمْرَأَتَكَ ۖ إِنَّهُۥ مُصِيبُهَا مَآ أَصَابَهُمْ ۚ إِنَّ مَوْعِدَهُمُ ٱلصُّبْحُ ۚ أَلَيْسَ ٱلصُّبْحُ بِقَرِيبٍۢ
(The messengers) said: O Lot! Lo! we are messengers of thy Lord; they shall not reach thee. So travel with thy people in a part of the night, and let not one of you turn round - (all) save thy wife. Lo! that which smiteth them will smite her (also). Lo! their tryst is (for) the morning. Is not the morning nigh?
Surah Hud(11:81)
