Why do you think anger would not apply to the Almighty? Better yet, why would he be angry?
It is not a difficult question, look at how many disobey. A few examples.. Take a look at the wasted mountains of food while a billion go to bed hungry. Look at how many take advantage of orphans, consuming their wealth. We live in an age where no sex before marriage is kinda a joke, but do you think this rule has changed? Is God somehow ok with fornication today when he condemned it yesterday?
There are many examples as the modern world is absolutely full of evil and corruption. From stealing a senior citizens home because they owe $10 in taxes to raping little kids.
How can you expect the Most High not to be angry?
It is said on the last day the Almighty will be so angry even the prophets will be scared. Look around you as there is plenty of reason for him to be. Justice is coming, like it or not.
Obviously nothing within the creation can be compared with the Almighty.
Far as we the creation are concerned, it is best to control our anger. Even when we are wronged.
Even when anger is warranted, it is best to forgive and forget.
I'm sure we have all had issues with anger,some worse then others. Those who have know how it eats away at you.
