Quran Al-A'raf 7:134
وَلَمَّا وَقَعَ عَلَيۡهِمُ ٱلرِّجۡزُ قَالُواْ يَٰمُوسَى ٱدۡعُ لَنَا رَبَّكَ بِمَا عَهِدَ عِندَكَۖ لَئِن كَشَفۡتَ عَنَّا ٱلرِّجۡزَ لَنُؤۡمِنَنَّ لَكَ وَلَنُرۡسِلَنَّ مَعَكَ بَنِيٓ إِسۡرَٰٓءِيلَ ١٣٤
Translation
And when the punishment descended upon them, they said, "O Moses, invoke for us your Lord by what He has promised you. If you [can] remove the punishment from us, we will surely believe you, and we will send with you the Children of Israel."
