A business partner of mine sold some silver coins in the market on credit, so I said, "Glory be to Allah! Is this permissible?"He replied, "Glory be to Allah! By Allah, I sold them in the market and no one criticized it."So I asked Bara bin Azib, who said, "The Prophet ﷺ arrived in Madinah while we were engaged in this kind of transaction, and he said, 'Whatever is hand to hand is fine, but whatever is on credit is not permissible.' Go and meet Zayd bin Arqam and ask him, for he was the greatest among us in trade."So I asked Zayd bin Arqam, and he said the same.
باع شريك لي دراهم في السوق نسيئة، فقلت: سبحان الله! أيصلح هذا؟ فقال: سبحان الله! والله لقد بعتها في السوق فما عابه أحد، فسألت البراء بن عازب، فقال: قدم النبي ﷺ ونحن نتبايع هذا البيع، فقال: ما كان يدا بيد فليس به بأس، وما كان نسيئة فلا يصلح. والق زيد بن أرقم، فاسأله؛ فإنه كان أعظمنا تجارة، فسألت زيد بن أرقم، فقال مثله.
Bukhari related it in the Book of Virtues (3939, 3940) from Ali bin Madini, and Muslim in the Book of Sharecropping (1589) from Muhammad bin Hatim bin Maymun, both of them from Sufyan bin Uyayna, from Amr, who heard Abu Minhal say what has already been mentioned. Their wording is the same. This should be understood as referring to the sale of the two different types.
