it's just a title of the Creator God,he's the best of creators. Btw, one of the main themes of the Quran is that the Creator God is by default, the only God. If one wishes to worship other deities, then they should produce evidence they exist, then the Quran goes on emphasizing the greatness of the Creator God, by pointing to His marvelous creation.
Yeah, that old chestnut. The world is beautiful therefore what Jesus/Allah/Yahweh said is true. Funny that the Qur'an uses this argument, and, significantly, never mentions diseases, famine, drought, etc, as evidences for His existence. Odd indeed that the All-Wise used an argument that even the simplest of religionists use, particularly when they haven't really thought it through.
Makes me think that even if the Qur'an were inspired, at least some of it would have to be Muhammad's (or someone else's) words.
