It was narrated from Sadaqah bin al-Muthanna : Riyah bin al-Harith told me, that
al-Mugheerah bin Shu"bah was in the Great Mosque, and the people of Koofah were with him, to his right and to his left. A man called Sa"eed bin Zaid came to him and al-Mugheerah greeted him and seated him by his feet on the couch. Then a man of Koofah came and turned to al-Mugheerah, and started spouting insults, Sa"eed said: Who is this man reviling, O Mugheerah? He said. He is reviling "Ali bin Abi Talib. He said: O Mugheer bin Shuʼb, O Mugheer bin shu’b - three times - why do i hear the Companions of the Messenger of Allah (ﷺ) being reviled in your presence and you do not object or try to stop it? I bear witness about the Messenger of Allah (ﷺ), that my ears heard and my heart understood it from the Messenger of Allah (ﷺ), and I have never narrated any lie about him that he would hold against me if I met him; (I bear) witness that he said: “Abu Bakr will be in Paradise, "Umar will be in Paradise, "Ali wili be in Paradise, "Uthman will be in Paradise, Talhah will be in Paradise, az-Zubair will be in Paradise, "Abdur-Rahman will be in Paradise and Sa"d bin Malik will be in Paradise." And the ninth of the believers who will be in Paradise - if you want me to name him, I shall name him. The people in the mosque started urging him, raising their voices, abjuring him: O Companion of the Messenger of Allah (ﷺ), who is the ninth? He said: As you have adjured me by Allah, and Allah is Almighty, I am the ninth of the believers, and the Messenger of Allah (ﷺ) is the tenth. Then he followed that with an oath. By Allah, one action of one of them who went out on campaign once and got his face dusty when he was with the Messenger of Allah (ﷺ) is better than all the actions of one of you, even if he were to live as long as Nooh .
