It is narrated from Sayyiduna Malik bin Nadlah al-Jushami (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) saw me in worn-out clothes and said: "Do you have wealth?" I said: Yes. He (peace and blessings be upon him) said: "What kind of wealth?" I said: Every kind; whatever Allah has given me. He (peace and blessings be upon him) said: "Then the blessing of Allah and His generosity towards you should be seen upon you."
