Dawud :: Book 39 : Hadith 4519
Narrated Aisha, Ummul Mu'minin:
The Prophet (peace_be_upon_him) sent AbuJahm ibn Hudhayfah as a collector of zakat. A man quarrelled with him about his sadaqah (i.e. zakat), and AbuJahm struck him and wounded his head. His people came to the Prophet (peace_be_upon_him) and said: Revenge, Apostle of Allah!
The Prophet (peace_be_upon_him) said: You may have so much and so much. But they did not agree. He again said: You may have so much and so much. But they did not agree. He again said: You may have so much and so much. So they agreed.
The Prophet (peace_be_upon_him) said: I am going to address the people in the afternoon and tell them about your consent.
They said: Yes. Addressing (the people), the Apostle of Allah (peace_be_upon_him) said: These people of faith came to me asking for revenge. I presented them with so much and so much and they agreed. Do you agree?
They said: No. The immigrants (muhajirun) intended (to take revenge) on them. But the Apostle of Allah (peace_be_upon_him) commanded them to refrain and they refrained.
He then called them and increased (the amount), and asked: Do you agree? They replied: Yes. He said: I am going to address the people and tell them about your consent. They said: Yes. The Prophet (peace_be_upon_him) addressed and said: Do you agree? They said: Yes.
