Udaysah bint Uhban (may Allah have mercy on her) narrates: "When Sayyiduna Ali (may Allah be pleased with him) came to Basrah, he came to (our) house and asked: 'Is Abu Muslim here?' We said: 'Yes.' So he came out to him, and Sayyiduna Ali (may Allah be pleased with him) said to him: 'Will you not help us in this matter?' He said: 'Certainly (see). O girl, bring me that sword.' She brought his sword, and it turned out to be a sword of wood. Abu Muslim said to him: 'Your cousin,' meaning the Prophet (peace and blessings be upon him), 'enjoined and emphasised to me that when there is fitnah (strife) among the Muslims, I should take a sword of wood.' Hearing this, Sayyiduna Ali (may Allah be pleased with him) turned away in anger and said: 'We have no need of you, nor of your sword.'" Yazid bin Zuray' (may Allah have mercy on him) said: "Yunus bin Ubayd (may Allah have mercy on him) had narrated this hadith to me from this shaykh before I met him."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Yunus bin Ubayd except Yazid bin Zuray'; Muhammad bin al-Minhal is alone in narrating it."
