حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، قَالَ قَرَأْتُ عَلَى مَالِكٍ عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم نَهَى عَنْ بَيْعِ الثَّمَرِ حَتَّى يَبْدُوَ صَلاَحُهَا نَهَى الْبَائِعَ وَالْمُبْتَاعَ.

Abu Huraira (Allah be pleased with him) reported Allah's Messenger (ﷺ) as saying

Do not buy the fruit until their condition is clear, and do not buy the fresh dates. A hadith like this has been reported by Ibn 'Umar through another chain of transmitters.
