in Edition Clear Qur'an by Talal Itani / An-Najm (The Star)

53:4It is but a revelation revealed.

53:22What a bizarre distribution.

53:23These are nothing but names, which you have devised, you and your ancestors, for which God sent down no authority. They follow nothing but assumptions, and what the ego desires, even though guidance has come to them from their Lord.

53:29So avoid him who has turned away from Our remembrance, and desires nothing but the present life.
