Surah An-Nisa — Ayah 110 (4:110)
وَمَن يَعۡمَلۡ سُوٓءًا أَوۡ يَظۡلِمۡ نَفۡسَهُۥ ثُمَّ يَسۡتَغۡفِرِ ٱللَّهَ يَجِدِ ٱللَّهَ غَفُورٗا رَّحِيمٗا ١١٠
English translation (Saheeh International)
And whoever does a wrong or wrongs himself but then seeks forgiveness of Allāh will find Allāh Forgiving and Merciful.
Brief commentary
If anyone does an evil action or wrongs themselves by committing sins, and then they ask for forgiveness from Allah, regretfully admitting their sin and leaving it, they will find that Allah is always ready to forgive their sins and show them mercy.
