Earthquakes have broken loose, and the tribes have lamented, for fear of God, the Lord of Strength, the All-Compelling.’ Say: ‘The stunning trumpet blast hath been loudly raised, and the Day is God’s, the One, the Unconstrained.’ ‘Hath the Catastrophe come to pass?’ Say: ‘Yea, by the Lord of Lords!’ ‘Is the Resurrection come?’ ‘Nay, more; He Who is the Self-Subsisting hath appeared with the Kingdom of His signs.’ ‘Seest thou men laid low?’ ‘Yea, by my Lord, the Exalted, the Most High!’ ‘Have the tree-stumps been uprooted?’ ‘Yea, more; the mountains have been scattered in dust; by Him the Lord of attributes!’ They say: ‘Where is Paradise, and where is Hell?’ Say: ‘The one is reunion with Me; the other thine own self, O thou who dost associate a partner with God and doubtest."...
