وَمَا ظَنُّ ٱلَّذِينَ يَفْتَرُونَ عَلَى ٱللَّهِ ٱلْكَذِبَ يَوْمَ ٱلْقِيَٰمَةِ ۗ إِنَّ ٱللَّهَ لَذُو فَضْلٍ عَلَى ٱلنَّاسِ وَلَٰكِنَّ أَكْثَرَهُمْ لَا يَشْكُرُونَ
And what think those who invent a lie concerning Allah (will be their plight) upon the Day of Resurrection? Lo! Allah truly is Bountiful toward mankind, but most of them give not thanks.
