Anas said:
When God's messenger gave orders for the oath of allegiance of God's good pleasure[*] `Uthman had gone to Mecca as God's messenger's messenger. Then when the people had taken the oath of allegiance God's messenger said, "`Uthman is engaged in God's business and in His messenger's business." He then struck one of his hands on the other, and God's messenger's hand on behalf of `Uthman was better than the people's hands on their own behalf.
*The oath of allegiance al-Hudaibiya. Cf. Quran, 48:18
Tirmidhi transmitted it.
