Sahl b. Abu Hathma reported Messenger of Allah ﷺ having forbidden Muzabana, i. e. exchange of fresh dates with dry dates. except in case of those to whom donations of some trees have been made. It is for them that concession has been given.
أَنَّ رَسُولَ اللَّهِ ﷺ نَهَى عَنِ الْمُزَابَنَةِ الثَّمَرِ بِالتَّمْرِ إِلاَّ أَصْحَابَ الْعَرَايَا فَإِنَّهُ قَدْ أَذِنَ لَهُمْ
