Praise be to Allāh Who is recognized without being seen and Who creates without trouble. He created the creation with His Might, and receives the devotion of rulers by virtue of His dignity. He exercises superiority over great men through His generosity. It is He who made His creation to populate the world and sent towards the jinn and human beings His messengers to unveil it for them, to warn them of its harm, to present to them its examples, to show them its defects and to place before them a whole collection of matters containing lessons about the changings of health and sickness in this world, its lawful things and unlawful things and all that Allāh has ordained for the obedient and the disobedient, namely, Paradise and Hell and honour and disgrace. I extend my praise to His Being as He desires His creation to praise Him. He has fixed “for everything a measure” (65:3), for every measure a time limit, and “for every time limit a document” (13:38).
