﴿ قُلْ إِنَّمَآ أُنذِرُكُم بِٱلْوَحْىِ ۚ وَلَا يَسْمَعُ ٱلصُّمُّ ٱلدُّعَآءَ إِذَا مَا يُنذَرُونَ ﴾

“SAY [unto all men]: “I but warn you on the strength of divine revelation!” But the deaf [of heart] will not hearken to this call, however often they are warned.”

(Say) to them, O Muhammad: (I warn you only by the Inspiration) by that which is revealed of the Qur'an. (But the deaf hear not the call when they are warned) but you cannot make hear he who pretends not to hear Allah's call.
