16- ابْنُ مَحْبُوبٍ عَنْ أَبِي أَيُّوبَ عَنْ سَمَاعَةَ قَالَ سُئِلَ أَبُو عَبْدِ اللهِ (عَلَيْهِ السَّلام) عَنِ الْعِنَبِ بِالزَّبِيبِ قَالَ لا يَصْلُحُ إِلا مِثْلا بِمِثْلٍ قُلْتُ وَالتَّمْرُ وَالزَّبِيبُ قَالَ مِثْلا بِمِثْلٍ.
16. Ibn Mahbub has narrated from abu Ayyub from Sama‘ah who has said the following: “Once abu ‘Abd Allah عليه السلام, was asked about the exchange of grape with raisins and he (the Imam) replied, ‘It is not permissible unless it is in equal measures.’ I asked about exchange of dates and raisins. He (the Imam) said, ‘It must be in equal measures.’”
