“I once asked him (the Imam); ‘Alayhi al-Salam, about the case of decorated swords in which there was silver sold for gold for an appointed time. He (the Imam) said, ‘People do not differ that on credit; it is Riba ’ (unlawful additional payment). They differ about the deal of hand in hand.’ I then asked, ‘Can he buy it with dirhams in cash?’ He (the Imam) said, ‘My father would say, “I like it to be along with something.’” I then asked, ‘What happens if dirhams given are more than the silver in it?’ He (the Imam) said, ‘How can they maintain precaution in it?’ I said that they think they know it. He (the Imam) said, ‘If they know it then it is not unlawful, otherwise, if they include something else along with it, is more desirable to me.”’
