Quran Al-Ahzab 33:71

يُصۡلِحۡ لَكُمۡ أَعۡمَٰلَكُمۡ وَيَغۡفِرۡ لَكُمۡ ذُنُوبَكُمۡۗ وَمَن يُطِعِ ٱللَّهَ وَرَسُولَهُۥ فَقَدۡ فَازَ فَوۡزًا عَظِيمًا

Translation

He will [then] amend for you your deeds and forgive you your sins. And whoever obeys Allāh and His Messenger has certainly attained a great attainment.
