Tafseer of aayah 2 from Surat Muhammad ﷺ.

Allah ﷻ Says:

وَالَّذِينَ آمَنُوا وَعَمِلُوا الصَّالِحَاتِ وَآمَنُوا بِمَا نُزِّلَ عَلَىٰ مُحَمَّدٍ وَهُوَ الْحَقُّ مِن رَّبِّهِمْ ۙ كَفَّرَ عَنْهُمْ سَيِّئَاتِهِمْ وَأَصْلَحَ بَالَهُمْ

"And those who believe and do righteous deeds and believe in what has been sent down upon Muhammad - and it is the truth from their Lord - He will remove from them their misdeeds and amend their condition"
