37359 - Abu Usamah narrated to us, from Ibn A'un, from Umayr ibn Ishaq, who said: "I entered with a man to visit Al-Hasan ibn Ali, and he kept saying to that man: 'Ask me before you can no longer ask me.' The man replied: 'I do not want to ask you anything that Allah will spare you from.' So he stood up, entered the lavatory, and then came out to us
and said: 'I did not come out to you until I expelled a portion of my liver, which I am now turning over with this stick, and I have been given poison to drink several times, but nothing is more severe than this time.' Then we came to him the next morning, and he was in the market. Al-Husayn came and sat by his head, saying: 'O my brother, who is your companion?' He replied: 'Do you want to kill him?' The man said: 'Yes.' He said: 'Then, if it is as I think, Allah will be more wrathful. And if he is innocent, I would not wish for an innocent person to be killed.'"
