أَمْ يَقُولُونَ ٱفْتَرَىٰ عَلَى ٱللَّهِ كَذِبًۭا ۖ فَإِن يَشَإِ ٱللَّهُ يَخْتِمْ عَلَىٰ قَلْبِكَ ۗ وَيَمْحُ ٱللَّهُ ٱلْبَٰطِلَ وَيُحِقُّ ٱلْحَقَّ بِكَلِمَٰتِهِۦٓ ۚ إِنَّهُۥ عَلِيمٌۢ بِذَاتِ ٱلصُّدُورِ
Or say they: He hath invented a lie concerning Allah? If Allah willed, He could have sealed thy heart (against them). And Allah will wipe out the lie and will vindicate the truth by His words. Lo! He is Aware of what is hidden in the breasts (of men).
