It is narrated from Sayyiduna Ali (may Allah be pleased with him) that he said: "I saw the Messenger of Allah (peace and blessings be upon him) in a dream, and I complained to him (peace and blessings be upon him) of the crookedness and fierce hostility I had faced from his Ummah, and I began to weep. He (peace and blessings be upon him) said to me: 'Do not weep, O Ali.' Then he (peace and blessings be upon him) turned to one side, and I turned the same way, and suddenly I saw two men being made to climb up, while their heads were being crushed with heavy rocks until they were shattered; then this (punishment) was repeated (in the same way) again." The narrator (Abu Salih (may Allah have mercy on him)) said: In the morning I set out, as was my habit, to visit Sayyiduna Ali (may Allah be pleased with him). When I reached the market of the leather-workers (al-Kharrazin), I met people who were saying that the Commander of the Faithful had been martyred.
