It is narrated from Sayyiduna Malik bin Nadlah al-Jushami (may Allah be pleased with him); he said: I came to the Prophet (peace and blessings be upon him) while I was in a shabby state, and he (peace and blessings be upon him) said to me: "Do you have wealth?" I said: Yes, camels, sheep and slaves. He (peace and blessings be upon him) said: "Then why is it not seen upon you?"
