'The Messenger of Allah ﷺ said: 'Dinar for Dinar, Dirham for Dirham, with no increase between them. Whoever has need of silver, let him trade gold for it, and whoever has need of gold, let him trade silver for it, and let the transaction be done on the spot."'
قَالَ رَسُولُ اللَّهِ ﷺ الدِّينَارُ بِالدِّينَارِ وَالدِّرْهَمُ بِالدِّرْهَمِ لاَ فَضْلَ بَيْنَهُمَا فَمَنْ كَانَتْ لَهُ حَاجَةٌ بِوَرِقٍ فَلْيَصْطَرِفْهَا بِذَهَبٍ وَمَنْ كَانَتْ لَهُ حَاجَةٌ بِذَهَبٍ فَلْيَصْطَرِفْهَا بِالْوَرِقِ وَالصَّرْفُ هَاءَ وَهَاءَ
