وَلَمَّا وَقَعَ عَلَيْهِمُ ٱلرِّجْزُ قَالُوا۟ يَٰمُوسَى ٱدْعُ لَنَا رَبَّكَ بِمَا عَهِدَ عِندَكَ ۖ لَئِن كَشَفْتَ عَنَّا ٱلرِّجْزَ لَنُؤْمِنَنَّ لَكَ وَلَنُرْسِلَنَّ مَعَكَ بَنِىٓ إِسْرَٰٓءِيلَ
43:50.
Commentary:
The words, according to that which He has promised to thee, may refer either to the promise which God made to Moses that He would listen to his prayers, or to the promise of God to forgive those who repented. The people of Pharaoh reminded Moses of these promises of God and asked him to pray to God in their behalf so that He might pardon them their sins and remove from them the punishments which had befallen them. The sentence may also mean, "pray for us to thy Lord, with the prayers which He has taught thee or in the way He has taught thee to pray."
43:50.
