Chapter 25: The Office of the Judge (Kitab Al-Aqdiyah)
Umm Salamah reported the Messenger of Allah (ﷺ) as saying: "I am only a human being, and you bring your disputes to me, some perhaps being more eloquent in their plea than others, so that I give judgement on their behalf according to what I hear from them. Therefore, whatever I decide for anyone which by right belongs to his brother, he must not take anything, for I am granting him only a portion of Hell.
Sunan Abi Dawud 3583
