A note Types of Alzheimer's and about Ammar bin Yasir, may God be pleased with him. He said: (A sign of the Mahdi's appearance is the influx of Turks upon you and that your Caliph who amasses wealth will die, and he will be succeeded by a weak man, who will be deposed after two years.) So the people of Yemen marched to fight him, as a reaction to his bombing of Yemen by planes, in the Yemen war with Saudi Arabia in 1436 AH - 2015 AD, and this is indicated by what we have previously mentioned of the words of Al-Walid: (Then they will march to him... to fight him - or - they will fight them.) And the people of Yemen will have the upper hand in their fight with the people of Hijaz, as indicated by what we have previously cited; the saying of Abdullah bin Amr bin Al-Aas, may God be pleased with them both, to the people of Yemen in the mosque of Damascus: (If I live to see that, I will be with the people of Yemen, and they will have the upper hand.) Dispute among three princes over the kingdom and their fighting. Then the royal family will dispute over the kingdom in the third generation, among the sons of the caliphs, who are the sons of sons, and three of them, all sons of a caliph and from the same family, will fight, and the kingdom will not go to any of them. The tribes will divide and fight in the holy places and in the forbidden months, and the sedition will strike them with its hand and its leg, and their gathering will end, and they will not unite under anyone except for months and days, and their reign will be cut off. Black banners will emerge upon them from the east and will kill them a killing that no people have killed before. There will be events in Shawwal and Dhu al-Qi'dah and their fighting during Hajj, as they will perform Hajj that year without an imam. And under these deteriorating conditions and security vacuum, the Mahdi will emerge. He will be pledged allegiance between the Rukn and the Maqam. And from Abdullah bin Amr, he said: (The people will perform Hajj together, and they will stand at Arafat together, without an imam. While they are descending in Mina, they will be seized by something like rabies, and the tribes will rise against each other, and they will fight until the Aqabah flows with blood. So they will flee to their best, and they will come to him while he is pressing his face to the ground.) - 56 -
