Khalifah mentioned that ʿAlī appointed Abū Ayyūb as governor of Medina. (1)
Al-Ḥākim said: Abū Ayyūb did not attend the battle of Ṣiffīn alongside ʿAlī.
Al-Aʿmash, on the authority of Abū Ẓabiyān:
Abū Ayyūb took part in a campaign during the rule of Muʿāwiyah, and when death came to him he said, “When you draw up your ranks against the enemy, bury me beneath your feet.” (2)
Ibn Fuḍayl narrated: Ibrāhīm al-Hajarī told us, from Abū Ṣādiq, who said:
Abū Ayyūb al-Anṣārī arrived in Iraq. The tribe of al-Azd presented him with several slaughtered camels, and I was with them. I greeted him and said, “O Abū Ayyūb, Allah has honored you with the companionship of His Prophet and with the Prophet’s lodging in your home; so why do I see you turning to face the people, fighting them with your sword?”
He replied, “The Messenger of Allah instructed us to fight alongside ʿAlī against the nākithīn (those who broke their pledge), and we have fought them; and against the qāsiṭīn (the unjust), and it is toward them we now advance”—meaning Muʿāwiyah—“and against the māriqīn (the renegades), and I have not yet met them.” (3)
This report is weak.
Isḥāq ibn Sulaymān al-Rāzī narrated: Abū Sinān, from Ḥabīb ibn Abī Thābit, that Abū Ayyūb came to Ibn ʿAbbās in Basra. Ibn ʿAbbās vacated a house for him and said, “I shall treat you as you treated the Messenger of Allah ﷺ. How much do you owe?”
He replied, “Twenty thousand.”
So Ibn ʿAbbās gave him forty thousand, twenty slaves, and the furnishings of the house. (4)
