When there was a delay in the returning of Uthman from Makkah, a rumor spread in the Muslim camp that Uthman had been killed by the Quraish of Makkah. That considerably upset the Muslims. At this juncture the Holy Prophet asked his followers to make a pledge with him to fight in the way of Allah to the bitter end. All the Muslims responded enthusiastically to the call. The Holy Prophet sat under a tree and all the Muslims in the camp took the pledge one by one. After every body had taken the pledge, the Holy Prophet placed his own right hand on his left hand, and took the pledge on behalf of Uthman. Uthman thus secured the unique honor that the Holy Prophet himself took the pledge on his behalf. About his ceremony of oath taking at Hudaibiyah, it was revealed in the Holy Quran:
"Surely, Allah was pleased with the believers when they took the pledge under the tree. Allah knew what was in their hearts. He sent down tranquillity upon them, and rewarded them with near victory".
In view of Allah's pleasure at the pledge taking., the pledge came to be known as "Baiy'at-ur-Ridwan".
Uthman returned from Makkah in the company of an emissary from the Quraish. On coming to know that in his absence the Muslims in the camp had taken the pledge, and the Holy Prophet had taken the pledge on his behalf, he took the pledge in person as well.
