(18) باب فِي التَّمْرِ بِالتَّمْرِ
Zayd Abu 'Ayyash asked Sa'd ibn Abi Waqqas about the sale of the soft and white kind of wheat for barley. Sa'd said:
Which of them is better? He replied: Soft and white kind of wheat. So he forbade him from it and said: I heard the Messenger of Allah (sawa) say, when he was asked about buying dry dates for fresh. The Messenger of Allah (sawa) said: Are fresh dates diminished when they become dry? The (the people) replied: Yes. So the Messenger of Allah (ﷺ) forbade that.Abu Dawud said: A similar tradition has also been transmitted by Isma'il b. Umayyah.
