Haqiqatul-Wahi 6 If someone were to ask, why does Satan disobey God Almighty when he is certain about His existence and Oneness? The answer to it is that his disobedience is not like the disobedience of man; he has been created for the trial of man with this very habit. This is a mystery the details of which have not been disclosed to man. It is the character of man that, mostly and overwhelmingly, he is guided aright by acquiring perfect knowledge about God Almighty, as Allah the Exalted says in the Holy Quran [‘Only those of His servants who possess knowledge fear Allah,’ (Surah Fatir, 35:29)]. However, those who have a satanic nature are outside this rule. (Author)
