وعن ابن مسعود رضي الله عنه
قال: «لعن رسول الله صلى الله عليه وسلم آكل الربا وموكله»
The Messenger of Allah (sallallahu alayhi wa sallam) cursed the one who accepts Ar-Riba (the usury) and the one who pays it. The narration in At-Tirmidhi adds: And the one who records it, and the two persons who stand witness to it.
