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) wearing poor clothes and in a poor state. The Messenger of Allah (peace and blessings be upon him) said to him: "Do you have wealth?" He said: Yes, every kind of wealth. He (peace and blessings be upon him) said: "Then let what Allah has provided you be seen upon you."
