H 74 - Ahmad bin Muhammad bin Isa has narrated from Saad bin Saad from Ahmad bin Umar from Imam Ali Ridha عليه السلام that he said with regard to Ibn Abi Hamza: Is he not one who narrated that the head of Mahdi was presented as a gift to Isa bin Musa, who is among the associates of Sufyani? He also said: Abu Ibrahim عليه السلام would return after eight months. Are the supporters of Abu Hamza not aware of his falsehood?
