﴿ يَٰقَوْمَنَآ أَجِيبُوا۟ دَاعِىَ ٱللَّهِ وَءَامِنُوا۟ بِهِۦ يَغْفِرْ لَكُم مِّن ذُنُوبِكُمْ وَيُجِرْكُم مِّنْ عَذَابٍ أَلِيمٍۢ ﴾

““O our people! Respond to God’s call, and have faith in Him: He will forgive you [whatever is past] of your sins, and deliver you from grievous suffering [in the life to come].”

O our people! Respond to God’s summoner Muhammad (s) by embracing faith and believe in him and He God will forgive you some of your sins because some of these sins are wrongs done to others and which therefore can only be forgiven after those wronged are reconciled — and shelter you from a painful chastisement.
