Surah Al-Anfal, ayah 29

يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓاْ إِن تَتَّقُواْ ٱللَّهَ يَجۡعَل لَّكُمۡ فُرۡقَانٗا وَيُكَفِّرۡ عَنكُمۡ سَيِّـَٔاتِكُمۡ وَيَغۡفِرۡ لَكُمۡۗ وَٱللَّهُ ذُو ٱلۡفَضۡلِ ٱلۡعَظِيمِ ٢٩

Yā'ayyuhal-ladhīna āmanū in tattaqullāha yaj'al lakum furqānan wayukaffir 'ankum sayyi'ātikum wayaghfir lakum wallāhu dhul-fadlil-'azīm

O you who have believed, if you fear Allāh, He will grant you a criterion⁴⁴⁴ and will remove from you your misdeeds and forgive you. And Allāh is the possessor of great bounty.
