He (peace and blessings be upon him) said: "What is this, O Bilal?" He replied: These are dates that I have stored up. He (peace and blessings be upon him) said: "Woe to you, O Bilal! Do you not fear that there will be smoke in the Fire because of it? Spend, O Bilal, and do not fear poverty from the Owner of the Throne."
