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.

Sayyiduna Uqbah bin Amir (may Allah be pleased with him) also narrated a similar hadith from the Noble Prophet (peace and blessings be upon him), except that in it, he said: The Prophet (peace and blessings be upon him) said: If you exercise ijtihad and reach the correct decision, you will receive ten rewards, and if you exercise ijtihad and make a mistake, you will receive one reward.

It is narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) that two men brought their case to Sayyiduna Amr bin Aas (may Allah be pleased with him). He judged between them, and the one against whom the decision was made became upset and went to the Messenger of Allah (peace and blessings be upon him) and complained. The Prophet (peace and blessings be upon him) said to him: When a judge gives a verdict and strives with full effort and makes the correct decision, he receives ten rewards, and if he makes a mistake despite his full effort, he still receives one or two rewards.

Narrated from Sayyiduna Amr bin Al-Aas (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: When a judge strives with full effort and reaches the correct decision, he receives two rewards, and when he makes a mistake despite striving with full effort, he receives one reward. This hadith is also narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him).

It is narrated from Sayyiduna Mu'adh bin Jabal (may Allah be pleased with him) that when the Messenger of Allah (peace and blessings be upon him) sent him as a governor to Yemen, he (peace and blessings be upon him) asked: "When a case is presented before you, how will you decide?" He said: "I will decide according to the Book of Allah." The Prophet (peace and blessings be upon him) said: "If the matter is not found in the Book of Allah, then what?" He said: "Then I will decide in the light of the Sunnah of the Messenger of Allah." The Prophet (peace and blessings be upon him) said: "If you do not find it in the Sunnah of the Messenger of Allah either, then what?" He said: "Then I will exercise my own judgment (ijtihad) and I will not fall short in doing so." Upon hearing this, the Messenger of Allah (peace and blessings be upon him) patted the chest of Sayyiduna Mu'adh (may Allah be pleased with him) and said: "All praise is due to Allah, Who has granted the messenger of the Messenger of Allah the ability to do that which pleases the Messenger of Allah."

It is narrated from Sayyiduna Ali (may Allah be pleased with him), he says: The Messenger of Allah (peace and blessings be upon him) appointed me as a judge to Yemen, while I was still young, so I said: O Messenger of Allah! You are sending me to a people among whom new matters arise, and I do not have knowledge of judging. The Prophet (peace and blessings be upon him) said: Allah Almighty will guide your tongue and strengthen your heart. After that, I never felt any doubt or uncertainty when deciding between two people.

It is narrated from Yazid bin Moheb that Sayyiduna Uthman (may Allah be pleased with him) said to Sayyiduna Abdullah bin Umar (may Allah be pleased with them both): Decide among the people. He replied: I will neither be a judge between two men nor an imam of two men. O Uthman! Did you not hear the Messenger of Allah (peace and blessings be upon him) say that whoever seeks refuge with Allah Almighty, he has sought a great refuge? Sayyiduna Uthman (may Allah be pleased with him) said: Yes, of course. He said: Then I seek refuge with Allah Almighty from you appointing me as an official. So Sayyiduna Uthman (may Allah be pleased with him) excused him, but said: Do not narrate this hadith to anyone else.

It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that when Hajjaj wanted to appoint his son as the judge of Basra, he said that the Messenger of Allah (peace and blessings be upon him) said: Whoever seeks the office of judge and tries to obtain it with the help of others, he will be entrusted with that office; and the person who neither seeks it nor takes the help of others to obtain it, Allah Almighty will send an angel for him who will guide him towards correctness.

(Second chain) It is narrated from Sayyiduna Anas (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Whoever seeks the position of judge for himself, it will be entrusted to him; and whoever is given it forcefully, an angel will descend upon him who will guide him towards what is better.

Imran bin Hattan says: I went to Lady Aisha (may Allah be pleased with her) and began to discuss with her, until the topic of the position of judge was mentioned. At that point, Lady Aisha (may Allah be pleased with her) said that the Messenger of Allah (peace and blessings be upon him) said: There will come a moment on the Day of Resurrection upon the judge when he will wish that he had not decided even about a single date between two men.
