Business Transactions
عَنْ صُهَيْبٍ - رضى الله عنه - أَنَّ اَلنَّبِيَّ - صلى الله عليه وسلم -قَالَ: { ثَلَاثٌ فِيهِنَّ اَلْبَرَكَةُ: اَلْبَيْعُ إِلَى أَجَلٍ، وَالْمُقَارَضَةُ، وَخَلْطُ اَلْبُرِّ بِالشَّعِيرِ لِلْبَيْتِ, لَا لِلْبَيْعِ } رَوَاهُ اِبْنُ مَاجَهْ بِإِسْنَادٍ ضَعِيفٍ [1] .
Narrated Suhaib (RA): The Prophet (ﷺ) said: "There are three things which contain blessings: A business transaction in which payment is agreed on a fixed later time, al-Muqaradah (speculative partnership), and mixing wheat and barley for one's household use but not for sale." [Reported by Ibn Majah through a Da'if (weak) chain of narrators].
