Narrated by:'Amr bin shu'aib
It was narrated from 'Amr bin shu'aib, from his father, from his grandfather, that:the Messenger of Allah prohibited lending on the condition of a sale, or to have two conditions in one transaction, or to profit from what you do not posses.
أَخْبَرَنَا إِسْمَاعِيلُ بْنُ مَسْعُودٍ، عَنْ خَالِدٍ، عَنْ حُسَيْنٍ الْمُعَلِّمِ، عَنْ عَمْرِو بْنِ شُعَيْبٍ، عَنْ أَبِيهِ، عَنْ جَدِّهِ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم نَهَى عَنْ سَلَفٍ وَبَيْعٍ وَشَرْطَيْنِ فِي بَيْعٍ وَرِبْحِ مَا لَمْ يُضْمَنْ .
