It is narrated from Sayyiduna Amr bin Aas (may Allah be pleased with him), he says: Two men brought a dispute to the Messenger of Allah (peace and blessings be upon him). The Prophet (peace and blessings be upon him) said to me: O Amr! Decide between them. I said: O Messenger of Allah! You are more deserving of this matter. The Prophet (peace and blessings be upon him) said: Even though I am. I said: If I decide between them, what will I get? The Prophet (peace and blessings be upon him) said: If you judge and reach the correct conclusion, you will get ten good deeds, and if you make a mistake in your judgment and err, you will get one good deed.
