Surah Ash-Shura (The Consultation), Verse 24

اَمْ یَقُوْلُوْنَ افْتَرٰی عَلَی اللّٰهِ كَذِبًا فَاِنْ یَّشَاِ اللّٰهُ یَخْتِمْ عَلٰی قَلْبِكَ وَیَمْحُ اللّٰهُ الْبَاطِلَ وَیُحِقُّ الْحَقَّ بِكَلِمٰتِهٖ اِنَّهٗ عَلِیْمٌۢ بِذَاتِ الصُّدُوْرِ ۟

Am yaqooloonaf tara 'alal laahi kaziban fa-iny yasha' illaahu yakhtim 'alaa qalbik; wa yamhul laahul baatila wa yuhiqqul haqqa bi Kalimaatih; innahoo 'Aleemun bizaatis sudoor

“What! Do they say, "He has forged a falsehood against Allah"? But if Allah willed, He could seal up thy heart. And Allah blots out Vanity, and proves the Truth by His Words. For He knows well the secrets of all hearts.”
