Ibn Umar (Allah be pleased them) reported Allah's Messenger (ﷺ) having forbidden Muzabana, and Muzabana implies the selling of fresh dates for dry dates by measuring them out and the selling of raisins by measure for grapes.
Sahih Muslim Book 21, Hadith 92
← Previous Hadith Abu Huraira (Allah be pleased with him) reported Allah's Messenger (ﷺ) having given exemption of 'ariyya transactions measuring less than five wasqs or up to five wasqs (the narrator Dawud is in doubt whether it was five or less than five).
