´'Udaisah bint Uhban bin Safi Al-Ghifari said:` "Ali bin Abi Talib came to my father to call him to go out(to fight) with him. My father said to him: 'Indeed my beloved, the son of your paternal uncle, made a covenant with me, that when the people differ, to take a sword of wood. So I have resigned it, if you wish I will take it out with you.' She said: 'So he left him."'

´‘Udaisah bint Uhban said:` “When ‘Ali bin Abu Talib came to Basrah, he entered upon my father and said: ‘O Abu Muslim, will 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 friend 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.’”

Benefits and Issues: (1) A wooden sword cannot be used in battle. The purpose of having a wooden sword made is to remain apart from fighting and conflict.
(2) At the time of mutual disagreement among Muslims, instead of supporting one of the parties, it is more important to try to reconcile both sides.
