As for 'Ali...

📌As for 'Ali, since he accepted the arbitration, but did not subsequently repent, he was killed as an unbeliever and his killing was a religious duty. Thus they denounced the caliphate of `Uthman after its seventh year, and that of 'Ali after the arbitration. [^8] They also abhorred the rest of the caliphs, and were always at war with them. Notes: [^6]. See sermon no.40, and also the commentary of Ibn Abi ' l-Hadid, vol.2, p.308 [^7]. See Ibn Kathir, al-Kamil fi 't-tarikh. [^8].
