(Ar-Rahman) 55 : 7
وَالسَّمَاءَ رَفَعَهَا وَوَضَعَ الْمِيزَانَ
And the sky, He raised it high; and He set up the Balance.
Lord became Impartial by teaching mankind Adhikr—the Balance and Trust to keep the universe in its equilibrium. As explained in verse 22: 65, the sky is not fallen upon the earth, except with Adhikr—the Permission. When the last forerunner who propagates Adhikr to the entire mankind returns to Paradise, the ten crucial signs of the Last Day will happen one by one, and in the last, the sky will fall upon the earth. See explanation 13: 2-4; 30: 25; and 42: 17.
