Musnad Imam Shafi'i

It is narrated from Malik bin Aws bin Hadthan that he needed to exchange 100 dinars (for dirhams). He stated: Talha bin Ubaidullah (may Allah be pleased with him) called me, and we discussed our matter until it was settled. He took the dinars and began turning them over in his hand, then said: "Let my male or female treasurer come from Ghaba." Imam Shafi’i (may Allah have mercy on him) said: I am doubtful about this. And Umar (may Allah be pleased with him) was listening to these things. He (may Allah be pleased with him) said: "By Allah! Do not separate from Talha until you take the money from him." Then he said: The Messenger of Allah (ﷺ) said: "Gold for gold, if not hand to hand, is usury; dates for dates, if not hand to hand, is usury; and barley for barley, if not hand to hand, becomes usury." Imam Shafi’i (may Allah have mercy on him) said: I read this hadith to Malik (may Allah have mercy on him) correctly without doubt, then a long time passed and I could not remember, so I became doubtful about 'khazini' and 'khazinatihi'. However, other narrators besides me narrate 'khazini' from Imam Malik (may Allah have mercy on him).

From another chain, it is narrated from Umar (may Allah be pleased with him) from the Prophet (ﷺ) similar to the hadith with Malik’s chain, and he said: “Until my treasurer comes.” Imam Shafi’i (may Allah have mercy on him) said, I remembered it without any doubt.

It is narrated from Umar bin Khattab (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "The sale of gold for silver, if not done on the spot, is usury; the sale of grain for grain, if not done on the spot, is usury; the sale of dates for dates, if not done on the spot, is usury; and the sale of barley for barley, if not done on the spot, is usury."

It is narrated from ‘Ubadah bin Samit (may Allah be pleased with him) that the Messenger of Allah (ﷺ) said: “Gold for gold, silver for silver, grain for grain, barley for barley, and salt for salt—equal for equal, specified for specified, and do not sell cash for anything but cash. But sell gold for silver, silver for gold, wheat for barley, barley for wheat, dates for salt, and salt for dates as you wish, hand to hand.” He said: “One of Muslim bin Yasar and the other man reduced the dates or the salt.” Abu al-‘Abbas said: In my book it is ‘from Ayyub from Ibn Sirin’, then I saw in the book of the shaykh, that is, Rabi’.

It is narrated from ‘Ubadah bin Samit (may Allah be pleased with him) that the Messenger of Allah (ﷺ) said: “Do not sell gold for gold, silver for silver, wheat for wheat, barley for barley, dates for dates, or salt for salt except equal for equal, same for same, and hand to hand. But sell gold for silver, silver for gold, wheat for barley, barley for wheat, dates for salt, and salt for dates as you wish, provided it is hand to hand.” One of them reduced the amount of dates or salt, and one of them added: “Whoever gives more or asks for more has engaged in usury.”
