3:175
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.
The Family of Imran

ٱلَّذِينَ قَالَ لَهُمُ ٱلنَّاسُ إِنَّ ٱلنَّاسَ قَدْ جَمَعُوا۟ لَكُمْ فَٱخْشَوْهُمْ فَزَادَهُمْ إِيمَـٰنًا وَقَالُوا۟ حَسْبُنَا ٱللَّهُ وَنِعْمَ ٱلْوَكِيلُ
Those to whom hypocrites said, "Indeed, the people have gathered against you, so fear them." But it [merely] increased them in faith, and they said, "Sufficient for us is Allah, and [He is] the best Disposer of affairs."
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.
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.
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.
