قَالُوا۟ They said تَقَاسَمُوا۟ Swear to each other بِٱللَّهِ by Allah لَنُبَيِّتَنَّهُۥ surely, we will attack him by night وَأَهْلَهُۥ and his family ثُمَّ Then لَنَقُولَنَّ we will surely say لِوَلِيِّهِۦ to his heir مَا Not شَهِدْنَا we witnessed مَهْلِكَ (the) destruction أَهْلِهِۦ (of) his family وَإِنَّا and indeed, we لَصَـٰدِقُونَ (are) surely truthful ٤٩
They said, "Take a mutual oath by Allāh that we will kill him by night, he and his family. Then we will say to his executor, 'We did not witness the destruction of his family, and indeed, we are truthful.'"
