It is narrated from Hazrat Thawban (may Allah be pleased with him) that when the blessed verse regarding gold and silver was revealed, people began to say, "What wealth should we keep with us?" Hazrat Umar (may Allah be pleased with him) said, "I will find out for you." So he quickly rode his camel and reached the Noble Prophet (peace and blessings be upon him), and I was also behind him. He submitted, "O Messenger of Allah! What wealth should we keep with us?" The Noble Prophet (peace and blessings be upon him) said, "A tongue that remembers (Allah), a grateful heart, and a believing wife who helps him in matters of the Hereafter."
