It is narrated from Sayyiduna Malik bin Nadlah al-Jushami (may Allah be pleased with him) that he came to the Prophet (peace and blessings be upon him) and began asking him (peace and blessings be upon him) questions. When the Prophet (peace and blessings be upon him) saw his poor state, he said: "Do you have wealth?" He said: Yes, every kind of wealth, which Allah has given me: camels, sheep and horses. He (peace and blessings be upon him) said: "When Allah gives you wealth, let it be seen upon you."
