“When Imam Ali (as) met with the people of Basra (in the battle of al-Jamal-the camel), he raised the banner of the Prophet (S) and their (people of Basra’s) legs began to shake. They were so until before the sunset when they said: “O ibn Abu Talib, safeguard!” Then Imam Ali (as) said to his army: “Do not kill the captives. Do not finish off the wounded. Do not follow after the fleers. Whoever lays down his arms is to be safe and whoever closes his door (stays at home) is to be safe.” When the battle of Siffeen broke out, Imam Ali’s companions insisted on him to raise the banner of the Prophet (S) but he refused. They sent to him his two sons al-Hasan and al-Husayn (as) and his close companion Ammar bin Yassir as mediators. He said to al-Hasan: “O my son, the people have a term that they must reach. No one is to raise this banner after me except al-Qa’im (as).”
