Uthman
Caliph Abu Bakr's era (632–634)

Uthman had a very close relationship with Abu Bakr, as it was due to him that Uthman had converted to Islam. When Abu Bakr was selected as the caliph, Uthman was the first person after Umar to offer his allegiance. During the Ridda wars (Wars of Apostasy), Uthman remained in Medina, acting as Abu Bakr's adviser. On his deathbed, Abu Bakr dictated his will to Uthman, saying that his successor was to be Umar.
