The Holy Quran 4:110 — Surah An-Nisa
Arabic text
وَمَن يَعْمَلْ سُوٓءًا أَوْ يَظْلِمْ نَفْسَهُۥ ثُمَّ يَسْتَغْفِرِ ٱللَّهَ يَجِدِ ٱللَّهَ غَفُورًا رَّحِيمًا
Translation
Whoever commits a (minor) sin or wrongs himself (by committing a major sin) and then seeks Allaah's forgiveness, he will surely find that Allaah is Most Forgiving, Most Merciful.
Tafsir (excerpt) — Tafsir Usmani
The difference between su' (evil) and zulm (wrongdoing): by su' (evil) and zulm (wrongdoing) are meant major and minor sins; or by su' is meant a sin through which pain reaches another, such as making an accusation against someone, and zulm is that whose harm stays within one's own self.
