﴿ قَالُوا۟ يَٰٓأَبَانَا ٱسْتَغْفِرْ لَنَا ذُنُوبَنَآ إِنَّا كُنَّا خَٰطِـِٔينَ ﴾

“[His sons] answered: "O our father! Ask God to forgive us our sins, for, verily, we were sinners."”

(They said) his children and grandchildren said: (O our father! Ask forgiveness of our sins for us) ask Allah to forgive our sins, (for lo! we were sinful) we were wrong-doers and disobedient towards Allah.
