رَحْمَةكَ

Appears 3 times in the Quran. (Root: رحم)
  1. He said: My Lord! forgive me and my brother and cause us to enter into Thy mercy, and Thou art the most Merciful of the merciful ones.

  2. And do Thou deliver us by Thy mercy from the unbelieving people.

  3. So he smiled, wondering at her word, and said: My Lord! grant me that I should be grateful for Thy favor which Thou hast bestowed on me and on my parents, and that I should do good such as Thou art pleased with, and make me enter, by Thy mercy, into Thy servants, the good ones.
