IBNHIBBAN 5019:
from Rasūl —
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.” (Using translation from Aḥmad 314)

عن رسول —
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»
