Sahih al-Bukhari, Hadith 1488 ⓘ
Narrated Anas bin Malik: Allah's Messenger forbade the selling of fruits until they were ripe. The Prophet (p.b.u.h) added, "It means that they become red."
حَدَّثَنَا قُتَيْبَةُ، عَنْ مَالِكٍ، عَنْ حُمَيْدٍ، عَنْ أَنَسِ بْنِ مَالِكٍ ـ رضى الله عنه ـ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم نَهَى عَنْ بَيْعِ الثِّمَارِ حَتَّى تُزْهِيَ، قَالَ حَتَّى تَحْمَارَّ.
