Establishing Only One Non Contingent Creator
If I understand your question correctly then If I ask you to define God, you wont give example you will define by attributes as there is nothing like it. We cannot comprehend the being. I think Ghamdi Sb meant the same. God is the cause of every thing as per Quran. How God effect things? we dont know as we havent been told. However, we can say since God is all powerful and all knowlegable, it can create any thing whenever it want.
Quran 42:11, 112:4 says there is nothing like it. Indeed Kalam Argument is the best argument to silence atheist because it philosophically proves God as necessary being without any begining or cause or precedator. So far athiests are unable to negate the single premise. Moreover,There is empirical evidence in favor of Kalam argument. But in my opinion, it fails to answer why God need to create human or send prophets for guidance or the concept of day of judgment in Islam seems meaningless. May be thats why there have been resistance to accept Kalam argument as the best argument. I will recommend you to watch webinars on this website. Hopefully you will get better understanding. https://www.gotostage.com/channel/sapienceinstitute
