﴿ وَمَن لَّا يُجِبْ دَاعِىَ ٱللَّهِ فَلَيْسَ بِمُعْجِزٍۢ فِى ٱلْأَرْضِ وَلَيْسَ لَهُۥ مِن دُونِهِۦٓ أَوْلِيَآءُ ۚ أُو۟لَٰٓئِكَ فِى ضَلَٰلٍۢ مُّبِينٍ ﴾

“But he who does not respond to God’s call can never elude [Him] on earth, nor can he has any protector against Him [in the life to come]: all such are most obviously lost in error.””

یغْفِرْ‌ لَكُم مِّن ذُنُوبِكُمْ (will forgive your sins for you,) The word 'min' used in the text gives the sense of 'some'. If it is taken in this sense here, it would mean that 'some sins' will be forgiven by embracing Islam. It will indicate that only sins relating to the rights of Allah would be forgiven but not the rights of people. But some exegetes have taken 'min' in this verse as an extra word that has no additional meaning in Arabic idioms. Given this interpretation, no explanation is required.
