Or it may be said:

It did not bring it into being before, so it does not do so now. Thus, whenever anything comes into being, the cause remains as it was before. Before that thing came into being, the cause was not bringing it into being; indeed, doing so was impossible. Likewise, at the time when it is supposed to come into being, its coming into being must be impossible.

Their most accomplished thinkers have acknowledged this as a necessary consequence, as Ibn Rushd, al-Rāzī and others have stated. They have acknowledged that something changing coming into being from something unchanging runs counter to the judgment of rational thinkers. Ibn Sīnā recognized this.
