[Machine] The Messenger of Allah ﷺ forbade us from selling silver for silver except for an equal amount, and from selling gold for gold except for an equal amount. And the Messenger of Allah ﷺ said, "Exchange gold for silver however you please, and exchange silver for gold however you please." Abu Abdur-Rahman narrated the news from my father, Tawbah, who came between Yahya ibn Abi Kathir and Abdur-Rahman ibn Abi Bakrah, Yahya ibn Abi Ishaq.  

نَهَانَا رَسُولُ اللهِ ﷺ أَنْ نَبِيعَ الْفِضَّةَ بِالْفِضَّةِ إِلَّا عَيْنًا بِعَيْنٍ سَوَاءً بِسَوَاءٍ وَلَا نَبِيعَ الذَّهَبَ بِالذَّهَبِ إِلَّا عَيْنًا بِعَيْنٍ وَسَوَاءً بِسَوَاءٍ وَقَالَ رَسُولُ اللهِ ﷺ «تَبَايَعُوا الذَّهَبَ بِالْفِضَّةِ كَيْفَ شِئْتُمْ وَالْفِضَّةَ بِالذَّهَبِ كَيْفَ شِئْتُمْ» قَالَ أَبُو عَبْدِ الرَّحْمَنِ خَبَرُ أَبِي تَوْبَةَ أَدْخَلَ بَيْنَ يَحْيَى بْنِ أَبِي كَثِيرٍ وَبَيْنَ عَبْدِ الرَّحْمَنِ بْنِ أَبِي بَكْرَةَ يَحْيَى بْنَ أَبِي إِسْحَاقَ
