قَالُوا۟ تَقَاسَمُوا۟ بِٱللَّهِ لَنُبَيِّتَنَّهُۥ وَأَهْلَهُۥ ثُمَّ لَنَقُولَنَّ لِوَلِيِّهِۦ مَا شَهِدْنَا مَهْلِكَ أَهْلِهِۦ وَإِنَّا لَصَٰدِقُونَ
They said: Swear one to another by Allah that we verily will attack him and his household by night, and afterward we will surely say unto his friend: We witnessed not the destruction of his household. And lo! we are truthtellers.
