Yahya ibn Yahya narrated to us, saying: I recited to Malik, from Abd al-Majid ibn Suhayl ibn Abd al-Rahman ibn Awf, from Sa'id ibn al-Musayyab, from Abu Sa'id al-Khudri and from Abu Hurayrah, that the Messenger of Allah, peace and blessings be upon him, appointed a man over Khaybar, and he brought him excellent-quality dates. The Messenger of Allah, peace and blessings be upon him, said to him: "Is all the dates of Khaybar like this?" He said: "No, by Allah, O Messenger of Allah. Indeed, we take one sa' of this for two sa' and two sa' for three." The Messenger of Allah, peace and blessings be upon him, said: "Do not do that. Sell the mixed dates for dirhams, then buy excellent-quality dates with the dirhams."
