That all Rizq (sustenance) is preordained in terms of its quantity and that Allah has taken its responsibility unto Himself. That we have a choice only in terms of what sources we would like to choose to obtain it and where we would like to spend it. That Shaytaan will try to frighten us with poverty while Allah comforts us with His Power. The Shaytaan has no power over the one who believes and seeks the protection of Allah. Action to take in case of difficulties with respect to sustenance.
