حَيَاتَكَ قَبْلَ مَوْتِكَ joins the earlier advice to a fundamental reality: during life, people can act, correct mistakes, and fulfill duties. When time is spent without purpose, achievable good deeds and necessary repairs may be repeatedly deferred.
A practical plan begins with one duty today: return a right that is owed, take a first step to correct a harmful practice, or reserve a small consistent period for study and worship. Realistic sustained actions are better than an impossible schedule. The narration aims to make present opportunity meaningful, not to induce helpless fear.
