Among the Major Signs, the most anticipated and central sign that Muslims are awaiting is the coming of a man known as, “The Mahdi.”  In Arabic, al-Mahdi means, “The Guided One” 1 He is also sometimes referred to by Shi’a Muslims as Sahib Al-Zaman or  Al-Mahdi al-Muntadhar which translated mean “The Lord of the Age” and “The Guided/Awaited One.”  The Mahdi is the first of the Major Signs.  This is confirmed by Ibn Kathir, the renowned Muslim scholar from the eighth century:

After the lesser signs of the Hour appear and increase, mankind will have reached a stage of great suffering.  Then the awaited Mahdi will appear; He is the first of the greater clear, signs of the Hour.2
