٥- مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ صَفْوَانَ عَنْ أَبَانٍ عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِي عَبْدِ اللهِ عَنْ أَبِي عَبْدِ اللهِ (عَلَيْهِ السَّلام) قَالَ نَهَى رَسُولُ اللهِ (صَلَّى اللهُ عَلَيْهِ وَآلِه) عَنِ الْمُحَاقَلَةِ وَالْمُزَابَنَةِ قُلْتُ وَمَا هُوَ قَالَ أَنْ تَشْتَرِيَ حَمْلَ النَّخْلِ بِالتَّمْرِ وَالزَّرْعَ بِالْحِنْطَةِ.
5. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Safwan from Aban from ‘Abd al- Rahman ibn abu ‘Abd Allah who has said the following: “Abu ‘Abd Allah , has said that the Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, prohibited al- Muhaqalah and al-Muzabanah .’ I then asked, ‘What are they?’ He (the Imam) said, ‘It is selling what a palm tree has just conceived in exchange for dates and green plantation for wheat.’”
