Al-Qaidah and ISIS are portents of the appearance of Hazrat Mahdi (pbuh)
96- Ghaibat Nomani: It is narrated from Ibne Uqdah from Ahmad bin Yusuf from Ibne Mahran from Ibne Bataini from his father from Wuhaib from Abu Basir from Imam Muhammad Baqir (a.s.) that he said: “The risings of Sufyani and Khurasani will be in the same period. They will be like the beads of a rosary; one following the other. Sufferings will be from every side. Miserable will be whoever resists them… The loss of the rule of the family of so-and-so will be like the breaking of pottery or like a man, who has a piece of pottery in his hand while he is walking. It falls from his hand while he is inattentive, but immediately he becomes attentive to find that it is broken. So is the loss of their rule. They will be so inattentive when their state will be lost.
