'Amr bin shu'aib said:"My father told me, mar rating from his father, from his father (and he mentioned 'Abdullah bin 'Amr) that he said: "The Messenger of Allah said: "It is not permissible to lend on the condition of a sale, or to stipulate two conditions in one transaction, or to make a profit on that which you do not possess.
أَخْبَرَنَا زِيَادُ بْنُ أَيُّوبَ، قَالَ حَدَّثَنَا ابْنُ عُلَيَّةَ، قَالَ حَدَّثَنَا أَيُّوبُ، قَالَ حَدَّثَنَا عَمْرُو بْنُ شُعَيْبٍ، قَالَ حَدَّثَنِي أَبِي، عَنْ أَبِيهِ، حَتَّى ذَكَرَ عَبْدَ اللَّهِ بْنَ عَمْرٍو قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " لاَ يَحِلُّ سَلَفٌ وَبَيْعٌ وَلاَ شَرْطَانِ فِي بَيْعٍ وَلاَ رِبْحُ مَا لَمْ يُضْمَنْ " .
