Euthyphro Problem & Islam

http://www.friesian.com/euthyph.htm#ten

excerpt:

The greatest systematization of the Will and Omnipotence of God may be found in Islâm, where, "God does what He wishes" [, Allâhu yaf'alu mâ yashâ'u], Qur'ân, Surah 3:40 (or 3:35). Or, as translated by Ahmed Ali [Al-Qur'ân, Princeton University Press, 1988, p. 215, Surah 13:31], "Have the believers not learnt that if God had so willed He could have guided all mankind?"

While Islâm is mostly prepared to pursue God's Omnipotence to its logical extreme, the Bible, Judaism, and Christianity are somewhat more tangled up in trying to preserve God's goodness and rationality.

excerpt:

If God is the Creator of absolutely everything, then He would be the Creator of all standards of value also. The Good would be posited by His own free, arbitrary, and omnipotent act of Will; and so it would be whatever he wanted it to be. However, this makes it senseless to praise God as being Good or to think of Him as in any way distinguished by His goodness. Whatever He thinks, wants, or does, it is simply good by definition, regardless of what it is. This is, at least, disappointing. On the other hand, if God recognizes what is good and wants to do it because it is good, this posits the nature of value independent of Him, so that he must, and wishes to, conform Himself to it. This makes it sensible to praise and revere God's goodness, but it also means that God is no longer the Creator of everything: standards of value stand above and beyond Him, outside of his control and creativity.
