Hadith 330

(The book) ‘Al Kharaij Wa Al Jaraih’ –
‘A group from the clan of Hashim gathered at Al-Abwa, from them were – Muhammad Bin Ali Bin Abdullah Bin Abbas, and Abu Ja’far Al Mansour, and Abdullah Bin Al-Hassan and his two sons Muhammad and Ibrahim, and they wanted to conclude a nomination to a man from them. Abdullah said, ‘This my son, he is Al-Mahdi’, and they sent a message to Ja’far-asws. He-asws came and said, ‘What have you all gathered for? ’ They said, ‘We are pledging allegiance to Abdullah for he is Al-Mahdi’. Ja’far-asws said: ‘Do not do it! ’
He-asws said: ‘But this and his brother and their sons are besides you all’, and he-asws struck his-asws hand upon the back of Al-Abbas, then said to Abdullah: ‘It (caliphate) will neither be to you nor to your two sons, but it is for the clan of Al-Abbas, and your two sons would be killed’. Then he-asws got up and said: ‘The owner of the yellow cloak, meaning Abu Ja’far, would kill him’. Abdul Aziz Bin Ali said, ‘By Allah-azwj! I did not exit from the world until I saw him kill, and the group was dissolved. Abu Ja’far said, ‘The caliphate would complete for me? ’ He said, ‘Yes, I am speaking the truth’’. [166]
