The Book of Transactions (Kitab Al-Buyu`)

Muslim :: Book 10 : Hadith 3870

Abu Huraira (Allah be pleased with him) reported that Allah's Messenger (may peace be upon him) deputed a person to collect revenue from Khaibar. He brought fine quality of dates, whereupon Allah's Messenger (may peace be upon him) said: Are all the dates of Khaibar like this)? He said: No. We got one sa' (of fine dates) for two sa's (of inferior dates), and (similarly) two sa's for three sa's. Thereupon Allah's Messenger (may peace be upon him) said: Don't do that rather sell the inferior quality of dates for dirhams (money), and then buy the superior quality with the help of dirhams.
