Quran 27:49 from Surah An-Naml on Divine Marvels.
قَالُواْ تَقَاسَمُواْ بِٱللَّهِ لَنُبَيِّتَنَّهُۥ وَأَهۡلَهُۥ ثُمَّ لَنَقُولَنَّ لِوَلِيِّهِۦ مَا شَهِدۡنَا مَهۡلِكَ أَهۡلِهِۦ وَإِنَّا لَصَٰدِقُونَ
English translation: They said Swear to each other by Allah surely we will attack him by night and his family Then we will surely say to his heir Not we witnessed (the) destruction (of) his family and indeed we (are) surely truthful."
Transliteration: qalu taqasamu bil-lahi lanubayyitannahu wa-ahlahu thumma lanaqulanna liwaliyyihi ma shahid'na mahlika ahlihi wa-inna lasadiquna
