Sahih al-Bukhari
Sahih al-Bukhari 2186
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، أَخْبَرَنَا مَالِكٌ، عَنْ دَاوُدَ بْنِ الْحُصَيْنِ، عَنْ أَبِي سُفْيَانَ، مَوْلَى ابْنِ أَبِي أَحْمَدَ عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ ـ رضى الله عنه أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم نَهَى عَنِ الْمُزَابَنَةِ وَالْمُحَاقَلَةِ. وَالْمُزَابَنَةُ اشْتِرَاءُ الثَّمَرِ بِالتَّمْرِ فِي رُءُوسِ النَّخْلِ.
Abdullah ibn Yusuf informed us: Malik informed us, from Dawud ibn al-Husayn, from Abu Sufyan, the freedman of Ibn Abi Ahmad, from Abu Said al-Khudri, may Allah be pleased with him, that the Messenger of Allah forbade muzabana and muhaqala. Muzabana is buying produce in exchange for dates while the dates are still on the palm trees.
Translation notes
The report names both muzabana and muhaqala but defines only muzabana here. The Arabic describes the dates as still on the palm trees.
