On the death of Abu Hudhaifa, Uthman assumed the guardianship of Muhammad b Hudhaifa. Muhammad b Abu Hudhaifa was brought up under the loving care of Uthman. Uthman treated him as a son. When Uthman became the Caliph, Muhammad bin Abu Hudhaifa desired that he should be made the Governor of some province. He wanted him to wait for some time as he was not yet fit for the high office of the Governor. That annoyed Muhammad b Abu Hudhaifa. He desired that in the circumstances he should be permitted to go somewhere else to seek his fortune. Uthman gave him some money and permitted him to go any where he liked. Muhammad b Abu Hudhaifa chose to go to Egypt.
