Somewhere I've heard, that emotions are transient things, but Allah is ethernal. And thus, Allah can't have emotions. It deeply surprised me, because I think, the only reason for the supreme being to create the world is the love. He doesn't need us, we can't give Him anything which he would need.
Thus, the only reason for Him to create us, is that He loves us. If you have a million of dollars, there is no problem for you to give a cent (or even much more) to a poor man.
But these are only my speculations.
Do the Quran mentions anything about Allah's emotions?
