(THE MASTER OF THE TIME - HAZRAT MAHDI (ATFS
وَ أَجِيءُ إِلَى يَثْرِبَ فَأَهْدِمُ الْحُجْرَةَ و أُخْرِجُ مَنْ بِهَا وَ هُمَا طَرِيَّانِ فَآمُرُ بِهِمَا تُجَاهَ الْبَقِيعِ وَ آمُرُ بِخَشَبَتَيْنِ يُصْلَبَانِ عَلَيْهِمَا فَتُورِقَانِ مِنْ تَحْتِهِمَا فَيَفْتَتِنُ النَّاسُ بِهِمَا أَشَدَّ مِنَ الْأُولَى فَيُنَادِي مُنَادٍ الْفِتْنَةُ مِنَ السَّمَاءِ يَا سَمَاءُ انْبِذِي وَ يَا أَرْضُ خُذِي فَيَوْمَئِذٍ لَا يَبْقَى عَلَى وَجْهِ الْأَرْضِ إِلَّا مُؤْمِنٌ قَدْ أَخْلَص
Imam Mahdi (a.t.f.s.) to Ali ibne Mahziyaar - …and I will go towards Yathrib (Medina)
and destroy al-Hujrah and evict those in it and those two (Abu Bakr and Umar l.a.) while they are fresh and order that they be hanged towards Baqee and order the two dried branches of their crucifixion to sprout leaves from below and people will be examined through them in a way more severe than before and a caller will call out as an examination – O sky leave (him) and O earth take (him). Then on that day, none shall remain on the face of the earth except a believer who has been purified.
