If Allah has the power of 'Kun Fa Ya Koon', then why do we hear of a certain number of days associated with the creation of this universe? Couldn't it have been done in an instant?
Bismillah
Thank you for your question. While the enactment God's Will is not limited by time, in His dealing with creation He chooses to work through processes and physical laws such as cause and effect. So while He can do whatever He wants in an instant, He chooses not to do that in every instance.
May you always be successful
