“I saw Yahya ibn ‘Umm Tawil standing at al-Kunasa (an open area in Kufah) calling at the peak of his voice, ‘O group of friends of Allah, I disavow whatever you hear. Whoever abuses Ali (a.s.) allow the condemnation of Allah be upon him. We renounce the people of the family of Marwan and all that they worship besides Allah.’ He then would lower his voice and say, ‘Do not sit with those who abuse the friends of Allah. Do not sit with those who doubt our belief and do not accept them as your judge. If any of your brothers (in belief) would need to ask you questions (help), then you have violated your trust with him (for not helping before his appeal).’ He then would read, ‘. . . For the unjust We have prepared a fire which will engulf them with its flames. Whenever they ciy for help they will be answered with water as hot as liquefied brass, which will blister their faces. How terrible is such a drink and such a resting place!”’ (18:29)
