Qur'an 7:134

وَلَمَّا وَقَعَ عَلَيْهِمُ ٱلرِّجْزُ قَالُوا۟ يَـٰمُوسَى ٱدْعُ لَنَا رَبَّكَ بِمَا عَهِدَ عِندَكَ ۖ لَئِن كَشَفْتَ عَنَّا ٱلرِّجْزَ لَنُؤْمِنَنَّ لَكَ وَلَنُرْسِلَنَّ مَعَكَ بَنِىٓ إِسْرَٰٓءِيلَ

And when the terror fell on them they cried: O Moses! Pray for us unto thy Lord, because He hath a covenant with thee. If thou removest the terror from us we verily will trust thee and will let the Children of Israel go with thee.
