وَعَنْ عَمْرِوِ بْنِ شُعَيْبٍ، عَنْ أَبِيهِ، عَنْ جَدِّهِ
قَالَ: قَالَ رَسُولُ اَللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ -«لَا يَحِلُّ سَلَفٌ وَبَيْعٌ وَلَا شَرْطَانِ فِي بَيْعٍ، وَلَا رِبْحُ مَا لَمْ يُضْمَنْ، وَلَا بَيْعُ مَا لَيْسَ عِنْدَكَ»
“The Messenger of Allah (sallallahu alayhi wa sallam) said: ‘The condition of a loan combined with a sale is not lawful, now two conditions relating to one transaction, nor the profit arising from something which is not in one’s charge, nor selling what is not in your possession.’.”
