Well Allah actually stated that his compassion has surpassed his wrath. I have read the old Testament, the New Testament and the Quran. The three Holy scriptures are from the same source; Allah. His statments about His oneness, mercy and actions did not change. Allah is constant He does not change. He already comprises All the attributes of perfection. many of them are of Beauty and others are only to warn his worshippers through.
Allah is Pardoning, Forgiving, Concealing, Compassionate, Mercy and Love, and on the other hand he manages to take venegance from those who do wrong.
If this Universe is a kingdom, then He is the king. Just like a kingdom cannot be a kingdom without a King, the universe cannot be a universe without Allah. Just as the Kingdom would fail to be a kingdom with more than one king the universe would fail to be a kingdom with more than one king. The matter is a Kingdom not a kingsdom. A kingdom, with one omnscient Powerful Creator, works right. What we see might be evil in out view point is positively what he sees and finds right in his point of view. It is the mere submission to his will and wish that makes one see the good doings of Allah. Whatever he does is good and is mercy even if it appeared the opposite.
I do testify that I worship The KING. I believe in his presence and I love his actions whatever they are, and however they appear.
