Umm Salamah (May Allah bepleased with her) reported:
Messenger of Allah (ﷺ) said, "Verily, I am only a human and the claimants bring to me (their disputes); perhaps some of them are more eloquent than others. I judge according to what I hear from them). So, he whom I, by my judgment, (give the undue share) out of the right of a Muslim, I in fact give him a portion of (Hell) Fire".[Al-Bukhari and Muslim].
