Hadith 8:66
Ibn Mas'ud reported God’s Messenger as saying, "Even though usury be much it leads in the end to penury.” Ibn Majah and Baihaqi, in Shu'ab al-iman, transmitted it, and Ahmad also transmitted it.
وَعَنِ ابْنِ مَسْعُودٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: " إِنِ الرِّبَا وَإِنْ كَثُرَ فإِنَّ عاقبتَه تصيرُ إِلى قُلِّ: رَوَاهُمَا ابْنُ مَاجَهْ وَالْبَيْهَقِيُّ فِي شُعَبِ الْإِيمَانِ. وَرَوَى أَحْمد الْأَخير
