"I would sell camels at Al-Baqi', so I would sell them for Dinar but take in place of them Dirham, and, I would sell for silver and take Dinar in its place. So I went to the Messenger of Allah ﷺ and found him leaving the house of Hafsah. I asked him about that and he said: 'There is no harm in that when it (equals) the price.'"
كُنْتُ أَبِيعُ الإِبِلَ بِالْبَقِيعِ فَأَبِيعُ بِالدَّنَانِيرِ فَآخُذُ مَكَانَهَا الْوَرِقَ وَأَبِيعُ بِالْوَرِقِ فَآخُذُ مَكَانَهَا الدَّنَانِيرَ فَأَتَيْتُ رَسُولَ اللَّهِ ﷺ فَوَجَدْتُهُ خَارِجًا مِنْ بَيْتِ حَفْصَةَ فَسَأَلْتُهُ عَنْ ذَلِكَ فَقَالَ لاَ بَأْسَ بِهِ بِالْقِيمَةِ
