Al A’raf Ayah 134

وَلَمَّا وَقَعَ عَلَيْهِمُ ٱلرِّجْزُ قَالُواْ يَـٰمُوسَى ٱدْعُ لَنَا رَبَّكَ بِمَا عَهِدَ عِندَكَ‌ۖ لَئِن كَشَفْتَ عَنَّا ٱلرِّجْزَ لَنُؤْمِنَنَّ لَكَ وَلَنُرْسِلَنَّ مَعَكَ بَنِىٓ إِسْرَٲٓءِيلَ ١٣٤ When tormented, they pleaded, “O Moses! Pray to your Lord on our behalf, by virtue of the covenant He made with you. If you help remove this torment from us, we will certainly believe in you and let the Children of Israel go with you.”
