The Family of Imran
وَلَا يَحْزُنكَ ٱلَّذِينَ يُسَـٰرِعُونَ فِى ٱلْكُفْرِ ۚ إِنَّهُمْ لَن يَضُرُّوا۟ ٱللَّهَ شَيْـًٔا ۗ يُرِيدُ ٱللَّهُ أَلَّا يَجْعَلَ لَهُمْ حَظًّا فِى ٱلْـَٔاخِرَةِ ۖ وَلَهُمْ عَذَابٌ عَظِيمٌ
And do not be grieved, [O Muhammad], by those who hasten into disbelief. Indeed, they will never harm Allah at all. Allah intends that He should give them no share in the Hereafter, and for them is a great punishment.

فَٱنقَلَبُوا۟ بِنِعْمَةٍ مِّنَ ٱللَّهِ وَفَضْلٍ لَّمْ يَمْسَسْهُمْ سُوٓءٌ وَٱتَّبَعُوا۟ رِضْوَٰنَ ٱللَّهِ ۗ وَٱللَّهُ ذُو فَضْلٍ عَظِيمٍ
So they returned with favor from Allah and bounty, no harm having touched them. And they pursued the pleasure of Allah, and Allah is the possessor of great bounty.
إِنَّمَا ذَٰلِكُمُ ٱلشَّيْطَـٰنُ يُخَوِّفُ أَوْلِيَآءَهُۥ فَلَا تَخَافُوهُمْ وَخَافُونِ إِن كُنتُم مُّؤْمِنِينَ
That is only Satan who frightens [you] of his supporters. So fear them not, but fear Me, if you are [indeed] believers.
إِنَّ ٱلَّذِينَ ٱشْتَرَوُا۟ ٱلْكُفْرَ بِٱلْإِيمَـٰنِ لَن يَضُرُّوا۟ ٱللَّهَ شَيْـًٔا وَلَهُمْ عَذَابٌ أَلِيمٌ
Indeed, those who purchase disbelief [in exchange] for faith - never will they harm Allah at all, and for them is a painful punishment.
وَلَا يَحْسَبَنَّ ٱلَّذِينَ كَفَرُوٓا۟ أَنَّمَا نُمْلِى لَهُمْ خَيْرٌ لِّأَنفُسِهِمْ ۚ إِنَّمَا نُمْلِى لَهُمْ لِيَزْدَادُوٓا۟ إِثْمًا ۚ وَلَهُمْ عَذَابٌ مُّهِينٌ
And let not those who disbelieve ever think that [because] We extend their time [of enjoyment] it is better for them. We only extend it for them so that they may increase in sin, and for them is a humiliating punishment.
