Didn’t you see that Lord Allah has subjected to you whatever is on the earth, the ships which run through the sea with His Command? And the sky is held without falling upon the earth, except with His Permission. Indeed Allah is Kind and Merciful upon mankind.
Command and Permission are two among the 40 names of Adhikr. It is told in verse 30: 25: “And of His Signs is that the heaven and earth exist with His Command Adhikr”. Since mankind is deputed to earth as the vicegerent of Lord, It is his inevitable duty to testify Adhikr and to convey It to entire mankind which is Balance and Trust to keep the universe in its equilibrium. But only 1 in 1000 believer will do it. And all other 999 out of 1000 Arabic Quran reading Fujjar by hiding and rejecting Adhikr are hurrying for Doomsday.
The 10 Crucial Signs of Doomsday will only occur after the departure of the last forerunner believer from the earth as explained in verse 6: 158. See explanation 5: 48; 10: 60-61 and 100.
