كُفْرهِمْ

Appears 5 times in the Quran. (Root: كفر)
  1. And they say: Our hearts are covered. Nay, Allah has cursed them on account of their unbelief; so little it is that they believe.

  2. And when We made a covenant with you and raised the mountain over you: Take hold of what We have given you with firmness and be obedient. They said: We hear and disobey. And they were made to imbibe (the love of) the calf into their hearts on account of their unbelief Say: Evil is that which your belief bids you if you are believers.

  3. Of those who are Jews (there are those who) alter words from their places and say: We have heard and we disobey and: Hear, may you not be made to hear! and: Raina, distorting (the word) with their tongues and taunting about religion; and if they had said (instead): We have heard and we obey, and hearken, and unzurna it would have been better for them and more upright; but Allah has cursed them on account of their unbelief, so they do not believe but a little.

  4. Therefore, for their breaking their covenant and their disbelief in the communications of Allah and their killing the prophets wrongfully and their saying: Our hearts are covered; nay! Allah set a seal upon them owing to their unbelief, so they shall not believe except a few.

  5. And for their unbelief and for their having uttered against Marium a grievous calumny.
