Sahih Bukhari, Chapter: Partnerships

I asked Abu Minhal about money exchange from hand to hand. He said, "I and a partner of mine bought something partly in cash and partly on credit." Al-Bara bin Azib passed by us and we asked about it. He replied, "I and my partner Zaid bin Al-Arqam did the same and then went to the Prophet (SAW) and asked him about it. He said, 'Take what was from hand to hand and leave what was on credit.' "
