(Al-An'aam) 6 : 67
لِكُلِّ نَبَإٍ مُسْتَقَرٌّ ۚ وَسَوْفَ تَعْلَمُونَ

For every prediction there is an appointed time, and soon you will be knowing it.

The Three-Time-Knower Lord of the universe says that for the happening of every sign there is a fixed time. It is told in verse 41: 53 that Lord will show them His verses in the horizons as well as in themselves until it becomes clear to them that indeed, It is the Truth. The separation of believers from mankind all over the world into Hejaz will be happening by the proclamation of Mahdi Ibnu Abdulla, who is the last Caliph of Islam as explained in verse 4: 159. Then the Arabic Quran reading Fujjar who hide and reject Adhikr will be banished and expelled from Hejaz. That event is called World Triumph as explained in verse 9: 28. See explanation 3: 7; 6: 4-5 and 55.
