I wanted to ask you how to answer the following question in the most logic and easy way: Can Allah create a stone which he himself cannot lift? Could that be the answer: Yes he CAN. But he doesn’t do it because he doesn’t do ungodly things therefore he doesn’t loose his almighty power? Please answer both.
Allah is capable of doing everything as He is the creator of the Heavens and the earth.
However, this relates to the possible and not the impossible.
If someone says: Can Allah create something he can’t move? We say that this is a stupid question! If Allah created it, Allah can move it. But the essence of your question is originally not correct and it is not this.
Your question is: Can Allah be incapable of doing something? This is not possible!
