41. Tārikh al-Tabari –narrating from `Abdullah ibn al-Hasan: “When `Uthmān was killed, the Ansār swore allegiance to Ali (a.s.), except for a few people such as: Hassān ibn Thābit, Ka`b ibn Mālik, Muslima ibn Mukhallad, Abu Sa`id al-Khudri, Muhammad ibn Maslima, al-Nu`mān ibn Bashir, Zaid ibn Thābit, Rāfi` ibn Khadij, Fadāla ibn `Ubayd and Ka`b ibn `Ujra. They were the followers of `Uthmān.
Then a man said to `Abdullah ibn Hasan: “How could they refuse to swear allegiance to Ali (a.s.) and (when we know that) they were followers of `Uthmān?”
He replied: “As for Hassān, he is a poet who does not care what he does; as for Zaid ibn Thābit, `Uthmān had appointed him as the head of the state council and Public Treasury and when `Uthmān was besieged, he said: “O group of Ansār, assist God Almighty”, repeating it twice. Abu Ayyub answered: “You will only assist him because he has put countless palm trees at your disposal”! As for Ka`b ibn Mālik, `Uthmān had used him to collect the alms tax of Muzayna and granted him what he had collected from them.”1
42. Waq`at Siffin –narrating from `Amr ibn Sa`d: “`Abdullah ibn `Umar, Sa`d ibn Abi Waqqās and al-Mughayra ibn Shu‘ba with a group of people went to visit Ali (a.s.) and they had not participated in swearing the allegiance to him. They asked him to
give them their share of the spoils, even though they did not take part in the battles of Siffin and Jamal.
Ali (a.s.) said to them: “What made you keep away from me?”
They said: “`Uthmān was killed and we do not know whether his blood was shed rightfully or not. He had committed some things and you made him repent and he did so. Then at the time of his killing, you contributed to it, so we do not know whether you acted rightfully or went wrong, even though we know of your excellence, O Commander of the Faithful, and your precedence [in Islam] and your migration (hijra).”
Ali (a.s.) then said: “Do you not know that God Almighty has commanded you to enjoin the good and forbid the wrong. He said: “If two groups of the faithful fight one another, make peace between them. But if one party of them aggresses against the other, fight the one which aggresses until it returns to Allah’s ordinance.”2
Sa`d said: “O Ali! Give me a sword that distinguishes the unbeliever from the believer. I fear that I may kill a believer and be taken to Hellfire.”
Ali (a.s.) told them: “Do you not know that `Uthmān was a leader to whom you swore allegiance to out of obedience? If he was righteous, why did you let him down? And if he was a wrongdoer, why did you not fight against him? If he was righteous, you did wrong since you did not help your leader, and if he was a wrongdoer, still you did wrong, as you did not help the person who asked others to practice good acts and refrained them from committing bad; and you did wrong, for you did not act between us and our enemy according to what you were commanded by God, as He said: “fight the one [party] which aggresses until it returns to Allah ordinances.”3 He then turned the group away and gave them nothing
