Sealed Hearts

This is how We seal the hearts of the disbelievers.

7:101Such were the townships. We relate some tidings of them unto thee (Muhammad). Their messengers verily came unto them with clear proofs (of Allah's Sovereignty), but they could not believe because they had before denied. Thus doth Allah print upon the hearts of disbelievers (that they hear not).

10:74Then, after him, We sent messengers unto their folk, and they brought them clear proofs. But they were not ready to believe in that which they before denied. Thus print We on the hearts of the transgressors.

30:59Thus doth Allah seal the hearts of those who know not.

40:35Those who wrangle concerning the revelations of Allah without any warrant that hath come unto them, it is greatly hateful in the sight of Allah and in the sight of those who believe. Thus doth Allah print on every arrogant, disdainful heart.
