Hadith 99

Bulugh al-Maram

Book 7: Business Transactions
وَعَنْ عَلِيٍّ ‏- رضى الله عنه ‏- قَالَ: قَالَ رَسُولُ اَللَّهِ ‏-صَلَّى اَللَّهُ عَلَيْهِ وَسَلَّمَ { كُلُّ قَرْضٍ جَرَّ مَنْفَعَةً, فَهُوَ رِبًا } رَوَاهُ اَلْحَارِثُ بْنُ أَبِي أُسَامَةَ, وَإِسْنَادُهُ سَاقِطٌ 1‏ .‏
'Ali (RA):

Allah's Messenger (ﷺ) said: "Every loan, which leads to a benefit, is usury." [al-Harith bin Abu Usamah reported it, but its chain of narrators is Saaqit (containing an extremely weak narrator)].
