An-Nisa' - 4:31

إِن تَجْتَنِبُواْ كَبَآئِرَ مَا تُنْهَوْنَ عَنْهُ نُكَفِّرْ عَنكُمْ سَيِّئَاتِكُمْ وَنُدْخِلْكُم مُّدْخَلاً كَرِيمًا
[4:31]
If you shun the great sins which you are forbidden, We will do away with your small sins and cause you to enter an honorable place of entering.
If ye (but) eschew the most heinous of the things which ye are forbidden to do, We shall expel out of you all the evil in you, and admit you to a gate of great honour.
If ye avoid the great (things) which ye are forbidden, We will remit from you your evil deeds and make you enter at a noble gate.
