It was narrated from Abu Saeed Al-Khudri that the Messenger of Allah said: "Do not sell gold for gold except like for like and do not differentiate. Do not sell silver for silver except like for like, and do not sell it in return for something to be paid later."

It was narrated that Abu Saeed Al-Khudri said: "My eyes saw and my ears heard the Messenger of Allah. And he mentioned the prohibition of (selling) gold for gold and silver for silver, unless it is equal amounts, like for like. And do not sell it in return for something to be paid later, and do not differentiate."

It was narrated from 'Ata' bin Yasir that: Muawiyah sold a cup of gold or silver for more than its weight. Abu Ad-Darda' said: "I heard the Messenger of Allah forbid such transactions unless it was like for like."

It was narrated the Fadalah bin 'Ubaid said: "On the Day of Khaibar I bought a necklace containing gold and ggems for twelve Dinars. The I took it apart and found that it contatined more than twelve Dinars. Mentiion of that was made to the Prophet and he said: 'It should not be sold until it is taken apart."

It was narrated that Fadalah bin 'Ubad said: "On the Day of Khaibar I got a necklace containing gold and gems, and I wanted to sell it. Mention of that was made to the Prophet and he said: 'Take it apart, and then sell it."'

It was narrated that abu Al-Minhal said: "Sharik sold some silver on credit for me. He came to me and told me. And I said: 'This is not correct.' He said; 'By Allah, I did this transaction in the market and no one criticized me .' So I went to Al-Bara bin Azib and asked him about that. He said: 'The Prophet came to us in Al-Madinah and we used to do this kind of transaction, but he said: Whatever is hand to hand, there is nothing wrong with it, but whatever is on credit, is Riba. Then he said to me: 'Go to Zaid bin Arqam.' So I went to him and asked him, and he said the same thing."

Abu Al-Minhal said: " I asked Al-Bara bin 'Azib and Zaid bin Arqam and they said: 'We were merchants at the time of the Messenger of Allah and we asked the Prophet of Allah about money exchange. He said: "If it is done hand to hand there is nothing wrong with it, but if it is done on credit then it is not right."

Abu Al-Minhal said: "I asked Al-Bara bin 'Azib about money exchange. He said: 'Ask Zaid bin Arqam, for he is better than me and more knowledgeable.' So I asked Zaid and he said: 'Ask Al-Bara for he is better than me and more knowledgeable.' And they both said: 'The Messenger of Allah forbade (selling) silver for gold on credit."'

'Abdur-Rahman bin Abi Bakrah narrated that his father said: "The Messenger of Allah forbade selling silver for silver and gold for gold, unless it was of equal amounts. And he told us to sell gold for silver however we wanted, and silver for gold however we wanted.
