H 436 - It is narrated from Kaabul Ahbar that he said: “When the owner of Ain [A’] from Bani Abbas comes to the throne; that is Abdullah, then this rule will begin with a person named Abdullah and end with a person named Abdullah. He will be the key to calamities and the sword of annihilation. When his announcement will be read in the evening, that: From the slave of Allah, Abdullah, the chief of believers, to the people of Syria: You will immediately come to know that the same is being announced from the pulpit of Egypt: From the slave of Allah, Abdullah, the chief of believers, to the people of Egypt…” When this happens, it will be the time of the decline of the kingdom of Bani Abbas. When this announcement is made by Bani Abbas in the morning, in the name of Abdullah you should wait till this announcement is made in the evening, in the name of Abdur Rahman and the latter will attack Abdullah in the cruelest way.”
