8- عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ هِشَامِ بْنِ سَالِمٍ عَنْ أَبِي عَبْدِ اللهِ (عَلَيْهِ السَّلام) قَالَ إِنَّمَا حَرَّمَ اللهُ عَزَّ وَجَلَّ الرِّبَا لِكَيْلا يَمْتَنِعَ النَّاسُ مِنِ اصْطِنَاعِ الْمَعْرُوفِ.
8. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Hisham ibn Salim who has said the following: “Abu ‘Abd Allah عليه السلام, has said that Allah, most Majestic, most Glorious, has prohibited receiving Riba’ so that people do not deny acts of benevolence and compassion.”
