[Machine] I heard the Messenger of Allah ﷺ say that exchanging like for like is not usury, except in the case of paper for paper, gold for gold, wheat for wheat, and barley for barley. This is mentioned in this narration: "Exchanging like for like" and the narration of the group in the raised hadith, as mentioned before.
سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ الْوَرِقُ بِالْوَرِقِ رِبًا إِلَّا هَا وَهَا وَالذَّهَبُ بِالذَّهَبِ رِبًا إِلَّا هَا وَهَا وَالْحِنْطَةُ بِالْحِنْطَةِ رِبًا إِلَّا هَا وَهَا وَالشَّعِيرُ بِالشَّعِيرِ رِبًا إِلَّا هَا وَهَا كَذَا فِي هَذِهِ الرِّوَايَةِ الْوَرِقُ بِالْوَرِقِ وَالذَّهَبُ بِالذَّهَبِ وَرِوَايَةُ الْجَمَاعَةِ فِي الْحَدِيثِ الْمَرْفُوعِ كَمَا مَضَى
