12. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from al- Hassan ibn Ali from Ali ibn Maysir who has said the following: “When Abu ‘Abdillah  went to meet Mansur al-‘Abbasi. He (Mansur) told his slave to stand ready and as soon as Abu ‘Abdillah  enters cut off his neck. When Abu ‘Abdillah  entered he looked at Mansur and said something to himself that he did not know what it was then he said out loud, ‘O the One who is sufficient for all of His creatures, and no one is sufficient for Him, suffice me against the evil of ‘Abd Allah ibn Ali. ’ Mansur turned to be as such that he could not see his slave and his slave could not see him. Mansur then said, ‘O Ja’far ibn Muhammad (it seems) we have caused you so much fatigue in this hot day, you may go back.’ Abu ‘Abd Allah  then left his office. Mansur asked his slave, ‘What stopped you from carrying my order?’ He said, ‘By Allah I could not see him, something came as a barrier between him and I.’ Abu Ja’far, Mansur said to him, ‘If you ever tell this to anyone I will kill you.’”
