17 Preface فَكَيفَ تَتَّقونَ إِن كَفَرتُم يَومًا يَجعَلُ الوِلدانَ شيبًاYusuf AliThen how shall ye, if ye deny (God), guard yourselves against a Day that will make children hoary-headed?-1If already you deny and disobey God in this life of probation, how can you stand up to the Day of Judgment, the Day of the terrible Reality? That Day is described in two metaphors; (1) It will be a time of such stress that even children will become like hoary-headed men; (2) What we look upon as the eternal sky, ever the same, will be cleft asunder; Cf. '82:1. In other words, the shape of things will be completely altered, both within man and in outer nature, and all true values will be restored. For the Promise of God, in this as in all other respects, cannot but be fulfilled.
