وَيَعْبُدُونَ مِن دُونِ ٱللَّهِ مَا لَمْ يُنَزِّلْ بِهِۦ سُلْطَٰنًۭا وَمَا لَيْسَ لَهُم بِهِۦ عِلْمٌۭ ۗ وَمَا لِلظَّٰلِمِينَ مِن نَّصِيرٍۢ
And they worship instead of Allah that for which He hath sent down no warrant, and that whereof they have no knowledge. For evil-doers there is no helper.
Surah Al-Hajj(22:71)

Sales and Trade
Chapter: Selling of Dinar for Dinar on credit
Narrated Abu Salih Az-Zaiyat:
I heard Abu Sa`id Al-Khudri saying, "The selling of a Dinar for a Dinar, and a Dirham for a Dirham (is permissible)." I said to him, "Ibn `Abbas does not say the same." Abu Sa`id replied, "I asked Ibn `Abbas whether he had heard it from the Prophet (ﷺ) s or seen it in the Holy Book. Ibn `Abbas replied, "I do not claim that, and you know Allah's Messenger (ﷺ) better than I, but Usama informed me that the Prophet had said, 'There is no Riba (in money exchange) except when it is not done from hand to hand (i.e. when there is delay in payment).' "
