And when it was established by this that this is the greatest misery, the decree was: because he did not purify himself, for he was not inclined towards fear. His saying, exalted is He, necessarily indicates the obligatory religion, which is avoidance and attraction. He combined avoidance and attraction with purification through devotion to the doors and constant adherence to the thresholds by complying with the command and avoiding the prohibition through the struggles that bring one closer to Him, glorified and exalted is He, the means of salvation after He warned against the destructive things. For hastening towards His beloved and pleasing things, gathering for worship that leads to the Creator after achieving perfection and completion, for there must be in a good life after belonging to the one of great status and following the one who does not deviate from the connection to an ideal way by which one achieves happiness to reach the intended goal and to fill his time with its duties so that he does not encounter a flaw or loss of precious moments nor negligence that would entice him by which the highway robbers would lead him: "Indeed, he has succeeded" meaning he has attained every desire, "who purifies himself" meaning he worked on purifying himself from corrupt beliefs, morals, sayings, actions, and wealth, and developing his inner and outer deeds, and giving charity from his wealth. This is the glorification that he commanded at the beginning of the Surah and what was not affected by it. Whoever does this is the happiest.
