1 Preface يا أَيُّهَا النّاسُ اتَّقوا رَبَّكُم ۚ إِنَّ زَلزَلَةَ السّاعَةِ شَيءٌ عَظيمٌYusuf AliO mankind! fear your Lord! for the convulsion of the Hour (of Judgment) will be a thing terrible!1As an introduction to the spiritual meaning of various symbolic acts in this life, the serious issues involved are indicated by showing how terrible the consequences will be for those who disobey God’s Will. The terror will only be for those who rebel and disobey: the righteous will not suffer from it, but on the contrary will be greeted by angels with joy (21:103).
