Sayyiduna Malik bin Nadlah (may Allah be pleased with him) narrates that I came to the Noble Prophet (peace and blessings be upon him), I had covered myself with one or two sheets and my condition was somewhat disheveled. The Prophet (peace and blessings be upon him) asked me: Do you have wealth? I said: Yes, absolutely, Allah Almighty has granted me all kinds of wealth—horses, camels, goats, and slaves. The Prophet (peace and blessings be upon him) said: If Allah Almighty has given you wealth, then the effects of His blessing should be visible on you. Upon hearing this, when I next went to the Prophet (peace and blessings be upon him), I was wearing a red garment.
