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."

" 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."

"I asked Al-Bara bin 'Azib about money exchange. He said: 'Ask Zaid bin Arqam, for he is better than me and more knowledgeable.'
