Criterion between right and wrong

يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓا۟ إِن تَتَّقُوا۟ ٱللَّهَ يَجْعَل لَّكُمْ فُرْقَانًا وَيُكَفِّرْ عَنكُمْ سَيِّـَٔاتِكُمْ وَيَغْفِرْ لَكُمْ ۗ وَٱللَّهُ ذُو ٱلْفَضْلِ ٱلْعَظِيمِ

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.
