Overall meaning : Say, Muhammad, ‘O Allah, Creator of the heavens and the earth, Knower of what is hidden from people and what they can see, You alone will judge between Your slaves on the Day of Resurrection with perfect justice regarding what they differ about in this life.’
Even if those who wrong themselves by associating partners with Allah possessed all that is on earth, and twice as much, they would surely offer it as a ransom in the hope of being saved from the terrible punishment on the Day of Resurrection. They will, on that day, be shown various types of Allah’s punishment which they have never imagined. The evil deeds they have committed in this life will be shown to them, and they will be overwhelmed by the very punishment which they have derided.
