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

“And whenever a plague struck them, they would cry: "O Moses, pray for us to thy Sustainer on the strength of the covenant [of prophethood] which He has made with thee! If thou remove this plague from us, we will truly believe in thee. and will let the children of Israel go with thee!"”

(And when the terror fell on them) whenever a torment fell on them such as the flood, locusts, vermin, frogs and blood (they cried: O Moses! Pray for us unto your Lord) ask your Lord for us, (because He hath a covenant with thee) because of that with which He has commanded you. (If thou removest the terror from us) if you remove the punishment from us (we verily will trust thee) we will believe in you (and will let the Children of Israel go with thee) with all their property.
