Surah Ali'Imran, Verse 177

إِنَّ ٱلَّذِينَ ٱشۡتَرَوُاْ ٱلۡكُفۡرَ بِٱلۡإِيمَٰنِ لَن يَضُرُّواْ ٱللَّهَ شَيۡـٔٗاۖ وَلَهُمۡ عَذَابٌ أَلِيمٞ١٧٧

inna alladhīna ish'tarawū l-kuf'ra bil-īmāni lan yaḍurrū l-laha shayan walahum ʿadhābun alīmun

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