And your Lord is Self-Sufficient, full of Mercy; if He wishes, He will remove you and will replace after you what He wishes just like He has produced you from the offspring of other people.
The Wise and Self Praiseworthy Lord of the universe is Self-sufficient and full of Mercy. He has deputed mankind to be His vicegerents as explained in verse 2: 30. For that He has given the Wise Reminder Adhikr mentioned in verse 3: 58, and has made It as the Balance and Trust to keep the universe in its equilibrium as explained in verse 3: 74. Gradually the people who inherited the Book rejected and forgot the Lord and the aim of life, and began to represent the disbeliever Satan. When most of the people of that period became wrongdoers, the Lord wiped out them completely after saving the Messenger and believers with him as explained in verses 6: 45-47. Then the believers and their offspring were also gradually diverted from the Straightpath by the influence of Satan belonging to Jinn and hypocritical leaders from mankind as explained in verse 6: 112. At last, Lord appointed Muhammad as the last Messenger and Prophet with the final version of the Book Adhikr as explained in verse 4: 163.
But after the thirty years of Messenger's departure, the Book reading people have become the Arabic Quran reading Fujjar who hide and reject Adhikr. By forgetting Adhikr, the Fujjar have become worthless and worst creatures as explained in verses 25: 18 and 8: 22. So Impartial Lord will entrust Adhikr to other people belonging to Messenger Muhammad’s community who will not hide and reject It as explained in verses 6: 89-90. So the odd believer should propagate Adhikr to entire worlds, especially to the other people who didn't receive It. See explanation 4: 85, 133; 6: 123, and 10: 47-48.
