Merciful

17:66Your Lord is He who propels for you the ships at sea, that you may seek of His bounty. He is towards you Most Merciful.

17:110Say, “Call Him God, or call Him the Most Merciful. Whichever name you use, to Him belong the Best Names.” And be neither loud in your prayer, nor silent in it, but follow a course in between.
