Excerpt from 'Nafasul Mahmum':
It is narrated that when the order was issued to hang Meytham he called out in a loud voice saying, 'O people! Whoever desires to listen to the mysterious sayings of the Commander of the faithful Ali (a.s.), come closer to me.' Hearing this people gathered around him and he started narrating the astonishing traditions. While this dignified personality (Allah’s Mercy be upon him), was among the abstinents and was such that the skin of his body had dried due to excessive worship and abstinence.
In Kitab al Gharat it is related by Ibraheem Saqafi, that Imam Ali (a.s.) had trained Meytham in abundant knowledge and concealed mysteries, which he would occasionally relate to the people, after hearing which the Kufans would fall in doubt and accuse Imam Ali (a.s.) of sorcery and deceit (for they could not digest and comprehend it). One day Imam Ali (a.s.), in the presence of a large gathering of some of his genuine followers as well as the skeptical ones said,
'O Meytham! After my death you will be seized and will be hanged. Then on the preceding day blood shall ooze from your nose and mouth, which will dye your beard. Then on the third day a weapon will be pierced in your stomach, which will result in your death, thus look forward to that day. The place where you shall be hanged is facing the house of ‘Amr bin Hurays. You shall be the tenth one from among those people who shall be hanged, while the timber of your gallow will be the shortest among all, and it will be nearer to the ground. And I shall show you the palm-tree on whose trunk you shall be hanged.'
Then after two days he showed him the palm-tree. Thereafter Meytham always came near the tree and recited Prayers and would say, 'What a blessed palm-tree you are, for you have been created and are growing up for me.'
After the martyrdom of Imam Ali (a.s.), Meytham often went to visit the palm-tree until it was cut down, then he looked after it’s trunks. He would go to ‘Amr bin Hurays and say, 'I will be your neighbor, thus fulfill the rights of neighborhood well.' ‘Amr would not understand his meaning and would ask, 'Do you intend buying the house of Ibn Mas’ood or Ibn Hakeem?'
Aqiqi relates that Abu Ja’far Imam Muhammad al Baqir (a.s.) held Meytham very dear, while Meytham was a believer, was grateful in prosperity and forbearing in adversity.
