Sahih Muslim | Book 18 | Hadith Number 4249

Narrated by Umm Salama
Umm Salama, the wife of Allah's Apostle (may peace be upon him), reported that Allah's

Messenger (may peace be upon him) heard the clamour of contenders at the door of his apartment. He went to them, and said: I am a human being and the claimants bring to me (the dispute) and perhaps some of them are more eloquent than the others. I judge him to be on the right, and thus decide in his favour. So he whom I, by my judgment, (give the undue share) out of the right of a Muslim, I give him a portion of Fire; he may burden himself with it or abandon it.
