There was a difference of opinion among the companions and supporters of Zayd ibn 'Ali, such as Abu al-Jarud Ziyad ibn Abi Ziyad, Sulayman ibn Jarir, Kathir al-Nawa al-Abtar and Hasan ibn Salih, concerning the status of the first three Caliphs who succeeded to the political and administrative authority of Muhammad. The earliest group, called Jarudiyya (named for Abu al-Jarud Ziyad ibn Abi Ziyad), was opposed to the approval of certain companions of Muhammad. They held that there was sufficient description given by the Prophet that all should have recognised 'Ali as the rightful Caliph. They therefore consider the Companions wrong in failing to recognise 'Ali as the legitimate Caliph and deny legitimacy to Abu Bakr, 'Umar and 'Usman; however, they avoid accusing them.
