It is narrated from Sayyiduna Ali (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "It is not proper for a Muslim to humiliate himself." The Companions said: "O Messenger of Allah, how does he humiliate himself?" He (peace and blessings be upon him) said: "He exposes himself to a trial that he does not have the strength to bear."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Abu Ishaq except Isra'il; al-Jarud is alone in narrating it, and this hadith is not narrated from Sayyiduna Ali (may Allah be pleased with him) except with this chain."
