…by “trumpet” is meant the trumpet-call of Muhammads Revelation, which was sounded in the heart of the universe, and by resurrection is meant His own rise to proclaim the Cause of God. He bade the erring and wayward arise and speed out of the sepulchres of their bodies, arrayed them with the beauteous robe of faith, and quickened them with the breath of a new and wondrous life. Thus at the hour when Muhammad, that divine Beauty, purposed to unveil one of the mysteries hidden in the symbolic terms “resurrection,” “judgment,” “paradise,” and “hell,” Gabriel, the Voice of Inspiration, was heard saying: “Erelong will they wag their heads at Thee, and say, ‘When shall this be?’ Say: ‘Perchance it is nigh.’” [Qur’án 17:51] The implications of this verse alone suffice the peoples of the world, were they to ponder it in their hearts.
