﴿ أَمْ يَقُولُونَ ٱفْتَرَىٰ عَلَى ٱللَّهِ كَذِبًۭا ۖ فَإِن يَشَإِ ٱللَّهُ يَخْتِمْ عَلَىٰ قَلْبِكَ ۗ وَيَمْحُ ٱللَّهُ ٱلْبَٰطِلَ وَيُحِقُّ ٱلْحَقَّ بِكَلِمَٰتِهِۦٓ ۚ إِنَّهُۥ عَلِيمٌۢ بِذَاتِ ٱلصُّدُورِ ﴾

“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. Verily, He has full knowledge of what is in the hearts [of men];”

(Or say they) in fact they do say: (He hath invented) Muhammad has invented (a lie concerning Allah?) The Prophet (pbuh) was saddened because of this, and so Allah, glorious and Exalted is He, said: (If Allah willed, He could have sealed) tied (thy heart (against them). And Allah will wipe out the lie) Allah will destroy idolatry and all the idolaters (and will vindicate the Truth by His words) and will manifest the religion of Islam through His enhancement. (Lo! He is aware of what is hidden in the breasts (of men)) He knows what is in people's hearts whether it is good or evil.
