The followers of Imam az-Zamaan [Hazrat Mahdi (as)] will not have an iota of doubt concerning Allah, the Allmighty and they will recognize Him as he ought to be recognized... (Al -Bayaan Fi Akhbaar - e -Mahdi Aakher al -Zamaan (a .s.) , chapter 5; Mikyaal al-Makaarem, vol. 1, p. 65)
The hadith refers to Hazrat Mahdi’s (as) followers’ depth of faith. Before the coming of Hazrat Mahdi (as) in the End Times, philosophies that deny Allah will be widely predominant. For that reason, there will be very few people who truly believe in Allah, fear Him and properly appreciate Him. But the followers of Hazrat Mahdi (as) will harbor a profound and unquestioning belief in Allah. This attribute will attract society’s attention toward them.
