quran:3:177 –

Indeed, those who purchase disbelief ˹in exchange˺ for faith - never will they harm Allah at all, and for them is a painful punishment.  

Those who purchase unbelief at the price of faith, that is, taking it in place of it, they will not hurt God at all, with their unbelief, and there awaits them a painful chastisement (alīm means mu’lim, ‘painful’).
القرآن:٣:١٧٧ –

إِنَّ الَّذِينَ اشْتَرَوُا الْكُفْرَ بِالْإِيمَانِ لَنْ يَضُرُّوا اللَّهَ شَيْئًا وَلَهُمْ عَذَابٌ أَلِيمٌ  

{إن الذين اشتروا الكفر بالإيمان} أي أخذوه بدله {لن يضروا الله} بكفرهم {شيئا ولهم عذاب أليم} مؤلم.
