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

Inna allatheena ishtarawoo alkufra bialeemani lan yadurroo Allaha shayan walahum AAathabun aleemun

Those who purchase Unbelief at the price of faith,- not the least harm will they do to Allah, but they will have a grievous punishment.
