دَّاع

Appears 3 times in the Quran. (Root: دعو)
  1. And when My servants ask you concerning Me, then surely I am very near; I answer the prayer of the suppliant when he calls on Me, so they should answer My call and believe in Me that they may walk in the right way.

  2. So turn (your) back on them (for) the day when the inviter shall invite them to a hard task,

  3. Hastening to the inviter. The unbelievers shall say: This is a hard day.
