يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓاْ إِن تَتَّقُواْ ٱللَّهَ يَجۡعَل لَّكُمۡ فُرۡقَانٗا وَيُكَفِّرۡ عَنكُمۡ سَيِّـَٔاتِكُمۡ وَيَغۡفِرۡ لَكُمۡۗ وَٱللَّهُ ذُو ٱلۡفَضۡلِ ٱلۡعَظِيمِ ٢٩
Translation
O you who have believed, if you fear Allāh, He will grant you a criterion and will remove from you your misdeeds and forgive you. And Allāh is the possessor of great bounty.
