عَنْ عَمْرِو بْنِ شُعَيْبٍ عَنْ أَبِيهِ عَنْ جَدِّهِ رَضِيَ اللَّهُ عَنْهُ قَالَ نَهَى رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ عَنْ بَيْعَتَيْنِ فِي بَيْعَةٍ وَعَنْ بَيْعٍ وَسَلَفٍ وَعَنْ رِبْحِ مَا لَمْ يُضْمَنْ وَعَنْ بَيْعِ مَا لَيْسَ عِنْدَكَ
It is narrated from Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) forbade making two sales in one transaction, combining sale and credit, profiting from something for which a person is not a guarantor, and selling something which is not in one’s ownership.
