Allah is the cause of all things, and the creator of all things. Allah is eternal, never ending and timeless, with no beginning or end. Him and all of his attributes are eternal and never ending. This might help you understand this question. Do you understand eternality in the abstract sense, do you have any abstraction that allows you to understand eternality? To put it, eternality here means never ending , however its the timeless eternality, something with no beginning and no end, Allah has no beginning and no end, if something has no beginning you can't apply seconds to it to count how long its existed because that doesn't apply to it. Unfortunately I've argued with lots of really dumb people, so I'm just going to say right now that the fact I'm showing a seeming contradiction is showing that I am starting to feel Allah isn't real, because him being the first cause seems to violate the law of non contradiction.
This post is showing a contradiction in the existence of a first cause, meaning maybe its not possible for it to exist. You might not get this immediately so look at the second paragraph and read again, for now just read this:can you get this: a first cause is eternal, meaning it is timeless, never ending. You can't apply seconds to it if it is eternal, all of its processes are eternal, its process of causation is also eternal,, all of its processes are eternal, and its process of causation is eternal, thus since its causation process doesn't end, it will continue to cause forever and ever, being eternal in the timeless sense, without a beginning and end. Now, I say this: if a first causes causation doesn't end, it will continue to cause and cause the exact same thing as its causation of that thing doesn't end, however, this means that the law of identity would be violated, because how can there be two of the same thing , if it continues to cause that thing then that would mean there are two things that are the same, but everything is equal to itself, it would go agains't the law of identity, so how do we overcome this contradiction? I thought of something like,non beings don't have properties, and this is important because of the fact that we can say that our abstract understanding is wrong, but then I thought of this: maybe we can't define the being abstractly since its trancendent, and other things but it seems i need help from smeone else on this.
Mind you, an inherent aspect of a first cause is its ability to cause, and its actual act of causing is also never ending, inherent here means it exists as a permanent aspect of it, because we know causation is an aspect of the first cause that is inherent to it, as if it wasn't permanent it would mean it had an aspect that was added to it, which is impossible because is eternal and timeless and can't change. So its causation being an inherent aspect of it is also eternal, and the process, non timely process which takes place in causing it is also never ending.
