Rejecting faith cannot harm Allah

خَتَمَ ٱللَّهُ عَلَىٰ قُلُوبِهِمْ وَعَلَىٰ سَمْعِهِمْ ۖ وَعَلَىٰٓ أَبْصَٰرِهِمْ غِشَٰوَةٌۭ ۖ وَلَهُمْ عَذَابٌ عَظِيمٌۭ

Allah hath set a seal on their hearts and on their hearing, and on their eyes is a veil; great is the penalty they (incur).

إِنَّ ٱلَّذِينَ كَفَرُوا۟ بِـَٔايَٰتِنَا سَوْفَ نُصْلِيهِمْ نَارًۭا كُلَّمَا نَضِجَتْ جُلُودُهُم بَدَّلْنَٰهُمْ جُلُودًا غَيْرَهَا لِيَذُوقُوا۟ ٱلْعَذَابَ ۗ إِنَّ ٱللَّهَ كَانَ عَزِيزًا حَكِيمًۭا

Those who reject our Signs, We shall soon cast into the Fire: as often as their skins are roasted through, We shall change them for fresh skins, that they may taste the penalty: for Allah is Exalted in Power, Wise.

أُو۟لَٰٓئِكَ هُمُ ٱلْكَٰفِرُونَ حَقًّۭا ۚ وَأَعْتَدْنَا لِلْكَٰفِرِينَ عَذَابًۭا مُّهِينًۭا

They are in truth (equally) unbelievers; and we have prepared for unbelievers a humiliating punishment.

فَإِن تَوَلَّوْا۟ فَقَدْ أَبْلَغْتُكُم مَّآ أُرْسِلْتُ بِهِۦٓ إِلَيْكُمْ ۚ وَيَسْتَخْلِفُ رَبِّى قَوْمًا غَيْرَكُمْ وَلَا تَضُرُّونَهُۥ شَيْـًٔا ۚ إِنَّ رَبِّى عَلَىٰ كُلِّ شَىْءٍ حَفِيظٌۭ

"If ye turn away,- I (at least) have conveyed the Message with which I was sent to you. My Lord will make another people to succeed you, and you will not harm Him in the least. For my Lord hath care and watch over all things."

قُلْ مَا يَعْبَؤُا۟ بِكُمْ رَبِّى لَوْلَا دُعَآؤُكُمْ ۖ فَقَدْ كَذَّبْتُمْ فَسَوْفَ يَكُونُ لِزَامًۢا

Say (to the Rejecters): "My Lord is not uneasy because of you if ye call not on Him: But ye have indeed rejected (Him), and soon will come the inevitable (punishment)!"

وَجَعَلْنَٰهُمْ أَئِمَّةًۭ يَدْعُونَ إِلَى ٱلنَّارِ ۖ وَيَوْمَ ٱلْقِيَٰمَةِ لَا يُنصَرُونَ

And we made them (but) leaders inviting to the Fire; and on the Day of Judgment no help shall they find.
