Indeed, there is ease with difficulty.
Mankind is deputed to the earth for undergoing a Trial. It is the natural law that there is a day after night, a descent for every ascent, and ease after difficulty. The Three-Time Knower, the Lord Allah, consoles the Messenger and the believers until the Last Day that the obstacles for propagating Adhikr will be removed, and the peace and tranquillity that Adhikr predicts will prevail throughout the world.
As explained in verse 48: 6, all regions except Hejaz — the province including Mecca and Medina — will be ruled by Antichrist, and Allah will send Prophet Jesus for the second time, and he will kill Antichrist. By that, Islam will become the single way of life throughout the world. See explanation 3: 140-141; 11: 17; 17: 81-82; 32: 29.
