باب بَيْعِ الْمُزَابَنَة، وَهْيَ بَيْعُ الثَّمَرِ بِالتَّمْرِ وَبَيْعُ الزَّبِيبِ بِالْكَرْمِ وَبَيْعُ الْعَرَايَا
Sahih al-Bukhari 2187

Narrated Ibn `Abbas:

The Prophet (ﷺ) forbade Muzabana and Muhaqala.

حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا أَبُو مُعَاوِيَةَ، عَنِ الشَّيْبَانِيِّ، عَنْ عِكْرِمَةَ، عَنِ ابْنِ عَبَّاسٍ ـ رضى الله عنهما ـ قَالَ نَهَى النَّبِيُّ صلى الله عليه وسلم عَنِ الْمُحَاقَلَةِ وَالْمُزَابَنَةِ‏.‏
