(15:49) [O Muhammad], inform My servants that it is I who am the Forgiving, the Merciful. (15:50) And that it is My punishment which is the painful punishment. (15:51) And inform them about the guests of Abraham, (15:52) When they entered upon him and said, "Peace." [Abraham] said, "Indeed, we are fearful of you." (15:53) [The angels] said, "Fear not. Indeed, we give you good tidings of a learned boy."
