“Once I went to Imam Ali (as) for some business. Then Ibnul Kawwa’ and Shibth bin Rib’iy came and asked permission to meet him. Imam Ali (as) said to me: “If you like to permit them, you can do that because you are the first to have your business achieved.” I said: “O Amirul Mo’mineen (as), permit them to come in.” When they came in, he said to them: “What made you secede from me in Haroora’?” They said: “We wanted to be with the army of anger.” He said: “Woe unto you! Is there any kind of anger in my guardianship? Anger comes after when many kinds of calamities and distresses occur. Then they (the army) gather like cloudlets of autumn; one, two, three, four, five, six, seven, eight, nine or ten from every tribe.”
