﴿ إِنَّا نَطْمَعُ أَن يَغْفِرَ لَنَا رَبُّنَا خَطَٰيَٰنَآ أَن كُنَّآ أَوَّلَ ٱلْمُؤْمِنِينَ ﴾

“Behold, we [but] ardently desire that our Sustainer forgive us our faults in return for our having been foremost among the believers!””

(Lo! we ardently hope that our Lord will forgive us our sins) our idolatry (because we are the first of the believers) in Moses.
