Mawla of the Messenger, Sayyiduna Thawban (may Allah be pleased with him) narrates that when this verse was revealed: "Those who hoard gold and silver and do not spend it in the way of Allah..." At that time, we were on a journey with the Messenger of Allah (peace and blessings be upon him). Some of us said to others: Something has been revealed regarding gold and silver, now if we could know which wealth is better so that we may strive for it. The Prophet (peace and blessings be upon him) said: The best wealth is a tongue that remembers (Allah), a heart that is grateful, and a believing wife who helps her husband in his faith.
