تَعْرِفُ

Appears 2 times in the Quran. (Root: عرف)
  1. And when Our clear communications are recited to them you will find denial on the faces of those who disbelieve; they almost spring upon those who recite to them Our communications. Say: Shall I inform you of what is worse than this? The fire; Allah has promised it to those who disbelieve; and how evil the resort!

  2. You will recognize in their faces the brightness of bliss.
