Wahabi says: If you believe that infinite regress in the past is impossible, then this dictates that Allah was completely actionless doing absolutely nothing, and in fact, not able to do anything prior to the creation of the world.
Comment: The statement “this dictates that Allah was completely actionless” is based on your own premise that Aļļaah exists in time and that His act of creating is itself an event, none of which Sunnis claim. You are also implying that Aļļaah must create to avoid imperfection.
Your claim “and in fact, not able to do anything” does not make sense even according to your own premise, which is the belief that Aļļaah’s actions are like ours, i.e. with a beginning and end. For example, I may want to do something tomorrow, in which case I will do nothing right now, but that does not mean I do not have the ability now. I have the ability, but I choose to do nothing. In any case, you are again saying that Aļļaah must create to have power.
According to your claims, you are saying that Aļļaah could not have chosen to not create anything, because that would make him something you call “actionless” and even powerless. In other words, He has no choice but to create in your view. In fact, you are saying that Aļļaah is imperfect if He does not create. This is a plain denial of the Aayah:
“يَا أَيُّهَا النَّاسُ أَنْتُمُ الْفُقَرَاءُ إِلَى اللَّهِ وَاللَّهُ هُوَ الْغَنِيُّ الْحَمِيدُ”,
Meaning: “O People, you are the desolate in absolute need of Aļļaah, and Aļļaah is the One that does not need anything or anyone, and He is the One that deserves all praise.” (Faaţir ,15)
How is having no choice compatible with godhood according to you people? Come back to Islam and believe that Aļļaah has no need to create.
