What did the Prophet Muhammad (peace be upon him) say about money exchanged from hand to hand?
 Narrated Sulaiman bin Abu Muslim:                     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 and asked him about it. He said, 'Take what was from hand to hand and leave what was on credit.' "
