عَرَفُوا۟

Appears 2 times in the Quran. (Root: عرف)
  1. And when there came to them a Book from Allah verifying that which they have, and aforetime they used to pray for victory against those who disbelieve, but when there came to them (Prophet) that which they did not recognize, they disbelieved in him; so Allah's curse is on the unbelievers.

  2. And when they hear what has been revealed to the messenger you will see their eyes overflowing with tears on account of the truth that they recognize; they say: Our Lord! we believe, so write us down with the witnesses (of truth).
