English Translation
Narrated Um Salama: Once Allah's Apostle said, "You people present your cases to me and some of you may be more eloquent and persuasive in presenting their argument. So, if I give some one's right to another (wrongly) because of the latter's (tricky) presentation of the case, I am really giving him a piece of fire; so he should not take it."
