Allah’s actions must be explained in terms of His all-encompassing knowledge and wisdom. There is nothing that Allah does but there is great wisdom behind it.  We may sometimes recognize the wisdom of Allah behind His creation or doing of certain things, but the general maxim maintains that “He cannot be questioned as to what He does, while they will be questioned” (Al-Anbiyaa’ 21:23)

 

Nevertheless, some scholars have attempted to explain the reason why the heavens and the earth were created in six days. Imam Al-Qurtubi, in commenting on Quran 7:54 maintained that Allah manifests His power to the angels gradually. Moreover, He decreed a course of action for everything in the universe. He, for example, delays a punishment he decreed for a sinful person and does not overtake him instantly.

 

Ibn al-Jawzi stated that doing things in a short time is more indicative of power, and His deliberation is more indicative of wisdom. Moreover, creation has been accomplished step by step, lest anyone would think that this happened as a result of an accident.
