Where is Allah (SWT)?

Allah (SWT) is above the heavens, raised over the Throne and separated from His creatures.  The proof is in the Quran:

And in a long Hadith found in Saheeh Muslim, it is narrated that the companion Mu`awiyah ibn al-Hakam, (RA) slapped his servant girl who used to tend his sheep, and as a result when to the Prophet (SAW) and asked what should be done as an atonement for having slapped her. The Prophet (SAW) replied, "Bring her to me" so Mu`awiyah brought her to the Prophet (SAW). The Prophet (SAW) then asked her, "Where is Allaah?" and she replied "Above the Sky" then the Prophet (SAW) asked her, "Who am I?" and she replied, "You are Allaah’s Messenger", so the Prophet (SAW) said, "Free her, for verily she is a true believer." (Saheeh Muslim, Vol 1, Hadith #1094, English Translation)

Is Allah (SWT) with us in person?

"Fear not, verily!  I am with you both, hearing, and seeing." (Ta-Ha 20:46)
