Sura al-Aʿrāf 7:134

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

wa-lammā waqaʿa ʿalayhimu l-rijzu qālū yā-musā idʿu la-nā rabbaka bi-mā ʿahida ʿindaka lain kashafta ʿannā l-rijza la-nuʾminanna la-ka wa-la-nursilanna maʿaka banī isrāʾīla

Every time the penalty fell on them, they said: "O Moses! on your behalf call on thy Lord in virtue of his promise to thee: If thou wilt remove the penalty from us, we shall truly believe in thee, and we shall send away the Children of Israel with thee."

Sura al-Dukhān 44:12

رَّبَّنَا ٱكْشِفْ عَنَّا ٱلْعَذَابَ إِنَّا مُؤْمِنُونَ

rabbanā ikshif ʿannā l-ʿadhāba innā muʾminūna

(They will say:) "Our Lord! remove the Penalty from us, for we do really believe!"
