We should not extend our hands for haram purposes. We should be concerned in our good deeds that we don't perform them for anyone else except Allah. Fear rips away desires and muddens luxuries so that cherished sins become reprehensible, just as a honey lover is repelled by it when he learns that it has poison in it. Hence, the heart becomes preoccupied with its own worries and looks towards its best interest in the long run. It is then engaged in only matters like meditation, self-analysis and struggle.
Fear has released their sleep, so they stand and acquire security in vigilance.
