Reading edition
Among those who entertained expectations of the Caliphate are named Abdallah son of Zobeir, the usurper of later days; and Mohammed son of Talha. Opinion varies as to whether Mohammed son of Abu Bekr was a candidate or not. Abdallah son of Omar was present, but without any pretensions to the Caliphate.
