that the Messenger of Allah said: "It is not permissible to lend on the condition of a sale, or to have two conditions in one transaction, or to sell what you do not have." (Sahih (Using translation from Nasāʾī 4611)
أَنَّ رَسُولَ اللهِ ﷺ قَالَ «لَا يَحِلُّ سَلَفٌ وَبَيْعٌ وَلَا شَرْطَانِ فِي بَيْعٍ وَلَا بَيْعُ مَا لَيْسَ عِنْدَكَ»
