(2). Knowledge. ('Ilm). He has knowledge of all things hidden or manifest, whether in heaven or on earth. He knows the number of the leaves of the trees, of the grains of wheat and of sand. Events past and future are known to Him. He knows what enters into the heart of man and what he utters with his mouth. He alone, except those to whom He has revealed them, knows the invisible things. He is free from forgetfulness, negligence and error. His knowledge is eternal: it is not posterior to His essence. (3). Power. (Qudrat). He is Almighty. If He wills, He can raise the dead, make stones talk, trees walk, annihilate the heavens and the earth and recreate of gold or of silver thousands similar to those destroyed. He can transport a man in a moment of time from the east to the west, or from the west to the east, or to the seventh heaven. His power is eternal a priori and a posteriori. It is not posterior to His essence. {118} (4). Will (Iradah). He can do what He wills, and whatever He wills comes to pass. He is not obliged to act. Everything, good or evil, in this world exists by His will. He wills the faith of the believer and the piety of the religious. If He were to change His will there would be neither a true believer nor a pious man. He willeth also the unbelief of the unbeliever and the irreligion of the wicked and, without that will, there would neither be unbelief nor irreligion. All we do we do by His will: what He willeth not does not come to pass. If one should ask why God does not will that all men should believe we answer: "We have no right to enquire about what God wills and does. He is perfectly free to will and to do what He pleases." In creating unbelievers, in willing that they should remain in that state; in making serpents, scorpions and pigs: in willing, in short, all that is evil God has wise ends in view which it is not necessary that we should know. We must acknowledge that the will of God is eternal and that it is not posterior to His essence. (5). Hearing. (Sama'). He hears all sounds whether low or loud. He hears without an ear for His attributes are not like those of men. (6). Seeing. (Basr). He sees all things, even the steps of a black ant on a black stone in a dark night; yet He has no eye as men have. (7). Speech. (Kalam). He speaks, but not with a tongue as men do. He speaks to some of His servants without the intervention of another, even as He spoke to Moses, and to Muhammad on the night of the ascension to heaven. He speaks to others by the instrumentality of Gabriel, and this is the usual way in which He communicates His will to the prophets. It follows from this that the Quran is the word of God, and is eternal and uncreated.
