Such imagined ideas which have equal relation called `mumkinul-wujud' -Possible, or Transient. They may exist in reality; they may not exist. There is nothing in their nature to demand this or that. So far as their nature is concerned, `To be' and `Not to be' both are equal to them. So far we have seen two categories of relationship between an imagined idea and its existence in reality with existence and non-existence, are Where that idea has equal relation with existence and non-existence.
It may exist; it may not exist. There is nothing in its nature to prefer either side. Where that idea can have absolutely no relation with existence. It, by its very nature is non-existence. It will appear from above classification that there should be a third category which would be opposite of `Impossible' ( mumtani`ul-wujud ) mentioned in (2) above. This third category is of the idea which can have absolutely no relation with non-existence. By its very definition, it is self-existent.
Such an idea is called ( wajibu'l wujud ) `Essential Existence' or 'Absolute Existence'. Now the picture is complete. Beginning Point of the World There is much conflict between the points of views of atheists and those who believe in a Supreme-Being Who created the world. Still, there is one important point where both are in complete agreement. Both agree that the basic source or cause of the universe is Eternal - has no beginning and no end; was always and will remain for ever.
In other words, it is 'self-existent' or 'wajibu'l-wujud'. The reason for this idea is very simple: As every thing in this universe falls under the category of `mumkinul-wujud' ` Transient,' it has equal relation with existence and non-existence. Once these things did not exist; now they exist; sometime in future they will cease to exist. By their nature, they cannot demand to exist or to cease to exist.
Therefore, there must be a source or cause to bring them to existence or to terminate their existence. And (it is the important point) that source or cause should not itself be just a ` Transient'; otherwise it will itself need a source or cause to bring into existence. And this chain of cause and effect must stop on a cause which needs no outside source or cause for its existence.
