Yahya related to me from Malik from Zayd ibn Aslam that Ata ibn Yasar said, "The Messenger of Allah (ﷺ) said, 'Dried dates for dried dates is like for like.' It was said to him, 'Your agent in Khaybar takes one sa for two.' The Messenger of Allah (ﷺ) said, 'all him to me.' So he was called for. The Messenger of Allah (ﷺ) asked, 'Do you take one sa for two?' He replied, 'Messengerof Allah! Why should they sell me good dates for assorted low quality dates, sa for sa!' The Messenger of Allah (ﷺ) said, 'Sell the assorted ones for dirhams, and then buy the good ones with those dirhams.' "
