Mukhtasar Bukhari

Narrated from Sayyiduna Malik bin Aws (may Allah be pleased with him) that he needed change for one hundred gold dinars. (He says that) Sayyiduna Talha bin Ubaidullah called for him and both of them discussed the matter until he agreed, and he began to turn the gold dinars over in his hand. After that, he said, "Wait for a while (O Malik bin Aws), by Allah! Do not leave Talha until you have taken the change from him (because) the Messenger of Allah (peace and blessings be upon him) said: 'Selling gold for gold is usury except when it is hand to hand...' and he narrated the entire hadith which has already been mentioned before."
