And if your Lord’s Word and a fixed term weren’t preceded, the punishment would have happened immediately.
In every Messenger’s period, the 999 out every 1000 people didn’t accept the Guidance Adhikr as explained in verse 11: 118-119. Impartial Lord didn’t destroy them unless they become wrongdoers and transgressors as explained in verse 6: 133.
Today, the Book is inherited by the people of the last Messenger. But by not utilizing and not giving It to others, they have become the wrongdoers and transgressors. So Lord will entrust Adhikr into other people who will not do so as explained in verses 6: 89-90. Shortly, by the proclamation of Caliph Mahdi in Hejaz, the hypocritical transgressors and Kuffar will be expelled from there. Then believers all over the world from mankind will be admitted there. Then by the departure of the last forerunner to Paradise pole shifting of earth and the emergence of the Antichrist will happen. See explanation 7: 24 and 10: 48-49.
