وَٱلَّذِينَ ءَامَنُواْ وَعَمِلُواْ ٱلصَّٰلِحَٰتِ وَءَامَنُواْ بِمَا نُزِّلَ عَلَىٰ مُحَمَّدٖ وَهُوَ ٱلۡحَقُّ مِن رَّبِّهِمۡ كَفَّرَ عَنۡهُمۡ سَيِّـَٔاتِهِمۡ وَأَصۡلَحَ بَالَهُمۡ
English translation: And those who believe and do righteous deeds and believe in what is revealed to Muhammad and it (is) the truth from their Lord He will remove from them their misdeeds and improve their condition
