The Prophet ﷺ said, "The selling of wheat for wheat is Riba (usury) except if it is handed from hand to hand and equal in amount. Similarly the selling of barley for barley, is Riba except if it is from hand to hand and equal in amount, and dates for dates is usury except if it is from hand to hand and equal in amount. (See Riba-Fadl in the glossary).  

عَنِ النَّبِيِّ ﷺ قَالَ الْبُرُّ بِالْبُرِّ رِبًا إِلاَّ هَاءَ وَهَاءَ وَالشَّعِيرُ بِالشَّعِيرِ رِبًا إِلاَّ هَاءَ وَهَاءَ وَالتَّمْرُ بِالتَّمْرِ رِبًا إِلاَّ هَاءَ وَهَاءَ  

that Malik bin Aus said, "I was in need of change for one-hundred Dinars. Talha bin 'Ubaidullah called me and we discussed the matter, and he agreed to change (my Dinars). He took the gold pieces in his hands and fidgeted with them, and then said, "Wait till my storekeeper comes from the forest." ʿUmar was listening to that and said, "By Allah! You should not separate from Talha till you get the money from him, for Messenger of Allah ﷺ said, 'The selling of gold for gold is Riba (usury) except if the exchange is from hand to hand and equal in amount, and similarly, the selling of wheat for wheat is Riba (usury) unless it is from hand to hand and equal in amount, and the selling of barley for barley is usury unless it is from hand to hand and equal in amount, and dates for dates, is usury unless it is from hand to hand and equal in amount"  

حَتَّى يَأْتِيَ خَازِنِي مِنَ الْغَابَةِ وَعُمَرُ يَسْمَعُ ذَلِكَ فَقَالَ وَاللَّهِ لاَ تُفَارِقُهُ حَتَّى تَأْخُذَ مِنْهُ قَالَ رَسُولُ اللَّهِ ﷺ الذَّهَبُ بِالذَّهَبِ رِبًا إِلاَّ هَاءَ وَهَاءَ وَالْبُرُّ بِالْبُرِّ رِبًا إِلاَّ هَاءَ وَهَاءَ وَالشَّعِيرُ بِالشَّعِيرِ رِبًا إِلاَّ هَاءَ وَهَاءَ وَالتَّمْرُ بِالتَّمْرِ رِبًا إِلاَّ هَاءَ وَهَاءَ  

I came saying who was prepared toexchange dirhams (for my gold), whereupon Talha b. Ubaidullah (Allah be pleased with him) (as he was sitting with 'Umar b. Khattib) said: Show us your gold and then come to us (at a later time). When our servant would come we would give you your silver (dirhams due to you). Thereupon 'Umar b. al-Khattib (Allah be pleased with him) said: Not at all. By Allah, either give him his silver (coins). or return his gold to him, for Messenger of Allah ﷺ said: Exchange of silver for gold (has an element of) interest in it. except when (it is exchanged) on the spot;and wheat for wheat is an interest unless both are handed over on the spot: barley for barley is interest unless both are handed over on the spot; dates for dates is interest unless both are handed over on the Spot.  

عُمَرُ بْنُ الْخَطَّابِ كَلاَّ وَاللَّهِ لَتُعْطِيَنَّهُ وَرِقَهُ أَوْ لَتَرُدَّنَّ إِلَيْهِ ذَهَبَهُ فَإِنَّ رَسُولَ اللَّهِ ﷺ قَالَ الْوَرِقُ بِالذَّهَبِ رِبًا إِلاَّ هَاءَ وَهَاءَ وَالْبُرُّ بِالْبُرِّ رِبًا إِلاَّ هَاءَ وَهَاءَ وَالشَّعِيرُ بِالشَّعِيرِ رِبًا إِلاَّ هَاءَ وَهَاءَ وَالتَّمْرُ بِالتَّمْرِ رِبًا إِلاَّ هَاءَ وَهَاءَ  

"The Messenger of Allah said: '(Exchanging) gold for silver is Riba unless it is done on the spot. (Exchanging) dates for dates is Riba unless it is done on the spot. (Exchanging) wheat for wheat is Riba unless it is done on the spot. (Exchanging) barley is Riba unless it is done on the spot."'  

قَالَ رَسُولُ اللَّهِ ﷺ الذَّهَبُ بِالْوَرِقِ رِبًا إِلاَّ هَاءَ وَهَاءَ وَالتَّمْرُ بِالتَّمْرِ رِبًا إِلاَّ هَاءَ وَهَاءَ وَالْبُرُّ بِالْبُرِّ رِبًا إِلاَّ هَاءَ وَهَاءَ وَالشَّعِيرُ بِالشَّعِيرِ رِبًا إِلاَّ هَاءَ وَ هَاءَ  

The Messenger of Allah ﷺ as saying: Gold for gold is interest unless both hand over on the spot ; wheat for wheat is interest unless both hand over on the spot ; dates for dates is interest unless both hand over on the spot ; barley for barley is interest unless both hand over on the spot.  

قَالَ رَسُولُ اللَّهِ ﷺ الذَّهَبُ بِالذَّهَبِ رِبًا إِلاَّ هَاءَ وَهَاءَ وَالْبُرُّ بِالْبُرِّ رِبًا إِلاَّ هَاءَ وَهَاءَ وَالتَّمْرُ بِالتَّمْرِ رِبًا إِلاَّ هَاءَ وَهَاءَ وَالشَّعِيرُ بِالشَّعِيرِ رِبًا إِلاَّ هَاءَ وَهَاءَ  

From Malik bin Aws bin Hadathan that he said: "I once said: 'Who can change some Dirham?' So Talhah bin 'Ubaidullah - and he was with 'Umar bin Al-Khattab - said: "Leave your gold with us, then return to us when our servant comes and we will give you your silver." 'Umar bin Al-Khattab said: "No! By Allah! Either give him his silver or return his gold to him. Indeed the Messenger of Allah ﷺ said: 'Silver for gold is Riba, except for hand to hand; and wheat for wheat is Riba except for hand to hand; and barley for barley is Riba except hand to hand; and dried-dates for dried-dates is Riba except for hand to hand.'"  

عُمَرُ كَلاَّ وَاللَّهِ لَتُعْطِيَنَّهُ وَرِقَهُ أَوْ لَتَرُدَّنَّ إِلَيْهِ ذَهَبَهُ فَإِنَّ رَسُولَ اللَّهِ ﷺ قَالَ الْوَرِقُ بِالذَّهَبِ رِبًا إِلاَّ هَاءَ وَهَاءَ وَالْبُرُّ بِالْبُرِّ رِبًا إِلاَّ هَاءَ وَهَاءَ وَالشَّعِيرُ بِالشَّعِيرِ رِبًا إِلاَّ هَاءَ وَهَاءَ وَالتَّمْرُ بِالتَّمْرِ رِبًا إِلاَّ هَاءَ وَهَاءَ  

"I heard 'Umar bin Al-Khattab say: 'The Messenger of Allah ﷺ said: "Exchanging gold for gold is usury unless it is done on the spot. (Exchanging) wheat for wheat is usury, unless it is done on the spot. (Exchanging) barley for barley is usury unless it is done on the spot. (Exchanging) dates for dates is usury, unless it is done on the spot."  

قَالَ رَسُولُ اللَّهِ ﷺ الذَّهَبُ بِالذَّهَبِ رِبًا إِلاَّ هَاءَ وَهَاءَ وَالْبُرُّ بِالْبُرِّ رِبًا إِلاَّ هَاءَ وَهَاءَ وَالشَّعِيرُ بِالشَّعِيرِ رِبًا إِلاَّ هَاءَ وَهَاءَ وَالتَّمْرُ بِالتَّمْرِ رِبًا إِلاَّ هَاءَ وَهَاءَ  

l brought some dinars of mine and wanted to exchange them. Talhah bin ‘Ubaidullah met me and we agreed to an exchange. Then he took them and said: Wait until my storekeeper comes - Abu ʿAmir said. From al-Ghalal (a place). And he said concerning it. All of it should be ‘Take this’ and ʿtake thisʿ [i.e., exchanged on the spot]. - I asked ‘Umar bin al-Khattab ؓ about that and he said: I heard the Messenger of Allah ﷺ say: ʿSilver for gold is riba, unless it is exchanged on the spot, wheat for wheat is riba, unless it is exchanged on the spot; barley for barley is riba, unless it is exchanged on the spot dates for dates is ribu unless it is exchanged on the spot.”  

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ الذَّهَبُ بِالْوَرِقِ رِبًا إِلَّا هَاءَ وَهَاتِ وَالْبُرُّ بِالْبُرِّ رِبًا إِلَّا هَاءَوَهَاتِ وَالشَّعِيرُ بِالشَّعِيرِ رِبًا إِلَّا هَاءَ وَهَاتِ وَالتَّمْرُ بِالتَّمْرِ رِبًا إِلَّا هَاءَ وَهَاتِ  

The Messenger of Allah ﷺ said ­- and on one occasion Sufyan said: ['Umar] heard the Messenger of Allah ﷺ say ­ “Gold for silver is riba unless it is exchanged on the spot [lit. ‘this for that'), wheat for wheat is riba unless it is exchanged on the spot, barley for barley is riba unless it is exchanged on the spot, dates for dates is riba unless it is exchanged on the spot.”  

قَالَ رَسُولُ اللهِ ﷺ وَقَالَ سُفْيَانُ مَرَّةً سَمِعَ رَسُولَ اللهِ ﷺ الذَّهَبُ بِالْوَرِقِ رِبًا إِلَّا هَاءَ وَهَاءَ وَالْبُرُّ بِالْبُرِّ رِبًا إِلَّا هَاءَ وَهَاءَ وَالشَّعِيرُ بِالشَّعِيرِ رِبًا إِلَّا هَاءَ وَهَاءَ وَالتَّمْرُ بِالتَّمْرِ رِبًا إِلَّا هَاءَ وَهَاءَ

عُمَرُ لَا تُفَارِقْهُ لَا تُفَارِقْهُ حَتَّى تُنْقِدَهُ قَالَ رَسُولُ اللَّهِ ﷺ «الذَّهَبُ بِالْوَرِقِ رِبًا إِلَّا هَاءً وَهَاتِ وَالْبُرُّ بِالْبُرِّ رِبًا إِلَّا هَاءً وَهَاتِ وَالشَّعِيرُ بِالشَّعِيرِ رِبًا إِلَّا هَاءً وَهَاتِ وَالتَّمْرُ بِالتَّمْرِ رِبًا إِلَّا هَاءً وَهَاتِ»
