Sahih al-Bukhari
Sahih al-Bukhari 2197
حَدَّثَنِي عَلِيُّ بْنُ الْهَيْثَمِ، حَدَّثَنَا مُعَلًّى، حَدَّثَنَا هُشَيْمٌ، أَخْبَرَنَا حُمَيْدٌ، حَدَّثَنَا أَنَسُ بْنُ مَالِكٍ ـ رضى الله عنه ـ عَنِ النَّبِيِّ صلى الله عليه وسلم أَنَّهُ نَهَى عَنْ بَيْعِ الثَّمَرَةِ حَتَّى يَبْدُوَ صَلاَحُهَا، وَعَنِ النَّخْلِ حَتَّى يَزْهُوَ. قِيلَ وَمَا يَزْهُو قَالَ يَحْمَارُّ أَوْ يَصْفَارُّ.
Ali ibn al-Haytham narrated to me: Mualla narrated to us: Hushaym narrated to us: Humayd informed us: Anas ibn Malik, may Allah be pleased with him, narrated from the Prophet that he forbade selling fruit until its ripeness became evident, and selling dates on the palm until they began to ripen. He was asked, “What does yizhu mean?” He replied, “It turns red or yellow.”
Translation notes
The report distinguishes general fruit from dates on the palm, and explains the ripeness sign for dates as turning red or yellow.
