‘Udaisah bint Uhbãn said: "When Ali bin Abu Tâlib came to Basrah, he entered upon my father and said: ‘O Abu Muslim,wll you not help me against these people? He said: ‘Of course.’ So he called a slave woman of his and said: ‘O slave woman, bring me my sword.’ So she brought it, and he unsheathed it a span, and (I saw that) it was made of wood. He said: ‘My close Mend and your cousin ﷺ advised me, if tribulation (Fitnah) arose among the Muslims, that I should take a sword of wood. If you wish I will go out with you.’ He said: ‘I have no need of you or of your sword.” (Hasan)
