Ahmed Raza Khan: Mohammed Aqib Qadri:
And those who, when they commit an immoral act or wrong themselves, remember Allah and seek forgiveness of their sins - and who forgives sins except Allah? And those who do not purposely become stubborn regarding what they did.

Yusuf Ali:
And those who, having done something to be ashamed of, or wronged their own souls, earnestly bring Allah to mind, and ask for forgiveness for their sins,- and who can forgive sins except Allah?- and are never obstinate in persisting knowingly in (the wrong) they have done.

Pickthal:
And those who, when they do an evil thing or wrong themselves, remember Allah and implore forgiveness for their sins - Who forgiveth sins save Allah only? - and will not knowingly repeat (the wrong) they did.
