People are victim to a host of afflictions, but the righteous are safeguarded. In fact, even those who are in their company find refuge. Hardship has no end. Even from within, man is plagued so severely by affliction that it is beyond imagination. Even if one takes the example of various illnesses, they are enough to result in countless other afflictions. But those who are within the fortress of righteousness are free from such affliction as distances one from God. However, those who are beyond its walls sit in a jungle teeming with ravenous beasts.
