1 Preface المYusuf AliA.L.M.1For these Abbreviated Letters see n. 25 to 2:1. We are asked to contrast, in our present life the real inner life against the outer life, and learn from the past about the struggles of the soul which uphold God’s Truth, against the environment of evil which resists it, and to turn our thoughts to the Ma'ad, or man’s future destiny in the Hereafter.
