اكفر

Appears 2 times in the Quran. (Root: كفر)
  1. One who had the knowledge of the Book said: I will bring it to you in the twinkling of an eye. Then when he saw it settled beside him, he said: This is of the grace of my Lord that He may try me whether I am grateful or ungrateful; and whoever is grateful, he is grateful only for his own soul, and whoever is ungrateful, then surely my Lord is Self-sufficient, Honored.

  2. Like the Shaitan when he says to man: Disbelieve, but when he disbelieves, he says: I am surely clear of you; surely I fear Allah, the Lord of the worlds.
