Khalifa Uthman bin Affan - Khirash b Umayyah

On the departure of Urwa, the Holy Prophet sent Khirash b Umayyah as an emissary to the Quraish. When he arrived in Makkah he was mar-treated by the Quraish, and the camel on which he rode was hamstrung. In turn the Quraish sent a detachment with the object of killing the Holy Prophet, and some of the prominent Muslims. These persons were taken captive by the Muslims. The companions wanted to kill them, but the Holy Prophet forbade the shedding of blood within the precincts of the sacred territory.

Uthman b Affan
Thereafter the Holy Prophet decided to send another emissary to the Quraish to negotiate terms of agreement with them. For such mission, a person had to be chosen who commanded influence with the Quraish. The choice fell on Uthman b Affan. Uthman b Affan accompanied by ten companions left for Makkah. Uthman went to Aban b Saeed b Aas an old friend. He welcomed Uthman, and gave him the necessary protection. Thereafter Uthman saw the principal Quraish leaders, and explained to them that the Muslims were on a mission of peace; their object was merely to perform the pilgrimage; and they wanted to extend the hand of friendship to the Quraish. The Quraish leaders said that if he wanted to perform the pilgrimage he was free to do so, but they could not allow the Muslims an entry in Makkah until an agreement was reached with them. Uthman said that he could not perform the pilgrimage unless the Holy Prophet performed the pilgrimage first. They said that they would send another emissary to the Muslim camp to arrive at some agreement with the Muslims. The Quraish took some time in nominating their emissary and during this period they detained Uthman at Makkah.
