The ninth Quality necessary in God is Knowledge (_ilm_). It is an eternal quality subsisting in the essence of God, an entity by which what is known is revealed with a revealing of the nature of complete comprehension (_ihata_), without any concealment having preceded. It is connected with the necessary, the possible and the impossible. He knows His own essence and qualities by His Knowledge. And He knows impossibilities in the sense that He knows that a partner is impossible to Him and that, if one existed, corruption would accrue from it. And Knowledge has an eternal, accomplished connection only. For God knows these things that have been mentioned from all eternity with a complete knowledge that is not by way of opinion (_zann_) or doubt (_shakk_); because opinion and doubt are impossibilities in God. And the meaning of the saying, “without any concealment having preceded,” is that He knows things eternally; He is not first ignorant of them and then knowing them. But an originated being (_hadith_) is ignorant of a thing and then knows it. And God’s Knowledge has no potential connection in the sense that there is a potentiality that such and such should be revealed by it, because that involves that the thing in question has not been actually revealed, and lack of actual revealing of it is ignorance. The tenth Quality necessary in God is Life (_hayah_). It is a quality which in him in whom it subsists validates perception, as knowledge and hearing and seeing: that is, it is valid that he should be described therewith. But being characterized by actual perception does not necessarily follow from possessing the quality, Life. And it is not connected with anything, entity or non-entity.
