﴿ وَٱلَّذِينَ ءَامَنُوا۟ وَعَمِلُوا۟ ٱلصَّٰلِحَٰتِ وَءَامَنُوا۟ بِمَا نُزِّلَ عَلَىٰ مُحَمَّدٍۢ وَهُوَ ٱلْحَقُّ مِن رَّبِّهِمْ ۙ كَفَّرَ عَنْهُمْ سَيِّـَٔاتِهِمْ وَأَصْلَحَ بَالَهُمْ ﴾

“whereas those who have attained to faith and do righteous deeds, and have come to believe in what has been bestowed from on high on Muhammad - for it is the truth from their Sustainer - [shall attain to God’s grace:] He will efface their [past] bad deeds, and will set their hearts at rest.”

(And those who believe) in Allah, Muhammad and the Qur'an (and do good works) acts of obedience, privately between them and their Lord: i.e. the Companions of Muhammad (pbuh) (and believe in that which is revealed unto Muhammad) and believe in that with which Allah sent down Gabriel to Muhammad (pbuh) (and it is) i.e. the Qur'an (the Truth from their Lord. He riddeth them of their ill deeds) i.e. their sins by means of jihad (and improveth their state) and improves their condition, intention and works in the life of he world; and it is said: He makes their matter manifest in Islam.
