وعن أبي أمامة رضي الله عنه عن النبي صلى الله عليه وآله وسلم قال : «من شفع لأخيه شفاعة فأهدى له هدية فقبلها فقد أتى بابا عظيما من أبواب الربا ». رواه أحمد وأبو داود وفي إسناده مقال.
Narrated Ibn 'Umar (RA): I heard Allah's Messenger (ﷺ) say, "If you sell anything on credit to anyone, on the condition that you will buy it back for a lower price (al-'Einah), take hold of the tails of cattle, become pleased with agriculture and give up Jihad - Allah will make disgrace prevail over you and will not remove it from you till you return to your religion." [Reported by Abu Dawud from the narration of Nafi' on the authority of Ibn 'Umar (RA), but there is a defect in its chain]. Ahmad reported something similar from the narration of 'Ata. Its narrators are reliable and Ibn al-Qattan graded it Sahih (authentic).
