A judge's letter to another judge

Amir regarded as actionable the sealed letter that came to him from a judge.

It is narrated from Umar bin Abi Za'idah: We came with a letter from the judge of Kufah to Iyas bin Mu'awiyah. When I arrived, Iyas had been removed and al-Hasan had been made judge. I gave my letter to him and he accepted it without questioning me about it. Then he opened the letter and spread it out, and found in it the testimony of two witnesses in my favour against a man of Basrah for five hundred dirhams. Then he said to a man standing by him: Take this to Ibn Ziyad and tell him to send him to so-and-so son of so-and-so, and to collect five hundred dirhams from him and give them to this man. The narrator said: So he took me there and he did so.

Ibrahim said: A judge's letter to a judge is valid, and it shall be put into effect.
