أَمْ يَقُولُونَ ٱفْتَرَىٰ عَلَى ٱللَّهِ كَذِبًا ۖ فَإِن يَشَإِ ٱللَّهُ يَخْتِمْ عَلَىٰ قَلْبِكَ ۗ وَيَمْحُ ٱللَّهُ ٱلْبَـٰطِلَ وَيُحِقُّ ٱلْحَقَّ بِكَلِمَـٰتِهِۦٓ ۚ إِنَّهُۥ عَلِيمٌۢ بِذَاتِ ٱلصُّدُورِ
Asad Quran Translation
DO THEY, perchance, say, "[Muhammad] has attributed his own lying inventions to God"? But then, had God so willed, He could have sealed thy heart [forever]: for God blots out all falsehood and by His words proves the truth to be true.30
Verily, He has full knowledge of what is in the hearts [of men];
See note  on 10:82 .
Malik Quran Translation
Do they say: "He has forged a falsehood against Allah?" But if Allah so willed, He could have sealed your heart. In fact Allah blots out falsehood and vindicates the truth by His words. Surely He knows everything that is hidden in your breast.
Yusuf Ali Quran Translation
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. 4562
If any one has a doubt about a prophet's mission, let him look at the prophet's lfe, at his work, at his character. Allah loves Truth, not Falsehood. Allah's aid goes with Truth, not with Falsehood. The beauty and power of Allah's Word cannot be found in Falsehood. The false man's heart would be sealed, not expanded to new heights, as is that of the Message-bearer of Allah.
Mustafa Khattab Quran Translation
Or do they say, “He has fabricated a lie about Allah!”? ˹If you had,˺ Allah would have sealed your heart, if He willed. And Allah wipes out falsehood and establishes the truth by His Words. He certainly knows best what is ˹hidden˺ in the heart.
Piktal Quran Translation
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).
