There are 11 attributes of God to look at in this comparison of Christian theology and Islamic theology:
-Omnipresence, Omnipotence, Omniscience, Omnitemporality (timelessness)
-Immutability (Unchanging)
-Immanence/ Transcendence, Holiness, Knowability
-Goodness, Love, and Justice
The primary focus in this one is God's goodness, Love, and Justice. Again, both faiths agree in theory. However, a love relationship is absent from the Quran but very prominent in the Bible. In addition, the Islamic view of God's holiness, goodness, and justice would seem to imply that God would have no means of bringing anyone to heaven.
