Umm Salama reported Allah's Messenger (ﷺ) as saying:
You bring to me, for (judgment) your disputes, some of you perhaps being more eloquent in their plea than others, so I give judgment on their behalf according to what I hear from them. (Bear in mind, in my judgment) if I slice off anything for him from the right of his brother, he should not accept that, for I sliced off for him a portion from the Hell.
