عن جابر رضي الله عنه قال: لعن رسول الله صلى الله عليه وسلم آكل الربا ومؤكله وكاتبه وشاهديه وقال: هم سواء (صحيح مسلم رقم 1598)

Hazrat Jaabir (radhiyallahu ‘anhu) reports that Rasulullah (sallallahu ‘alaihi wasallam) cursed the one who consumes interest, the one who feeds it to others, the one who records the interest transaction and the two witnesses of the transaction, and Rasulullah (sallallahu ‘alaihi wasallam) mentioned that they are all equal (in committing sin).
