While I might feel it is a combination of both, the evidence is that TBN is all for the blending of Christianity and Islam, since they recently dropped Jack Van Impe's show after he began talking against Rick Warren and the Crystal Cathedral stances and employment of finding common ground between Christianity and Islam.

You can do your own research on the apostasy of the teaching Chrislam, here:
Rick Warren’s Chrislam Starts To Spread In America
What is Chrislam and Who Teaches It?
As Christians we should know who the Almighty, Most High God is...if we don't, then how can we call ourselves followers of Jesus Christ...then again, there's often a deep divide between those that call themselves "Christian" and those that are followers of Jesus Christ..
However, many...if not most Christians, even followers of Jesus Christ, have no idea who Allah is. In fact, all too many of them think he is the same God as Jehovah God, just with a different name. However, while God the creator can be traced back to...well, creation, no where in the Bible do we see Him identified in any language as "Allah".
But in Isaiah 14, we see the passage where it describes the fall of Lucifer:
Isa 14:12 How art thou fallen from heaven, O Lucifer, son of the morning! how art thou cut down to the ground, which didst weaken the nations!
Isa 14:13 For thou hast said in thine heart, I will ascend into heaven, I will exalt my throne above the stars of God: I will sit also upon the mount of the congregation, in the sides of the north:
Isa 14:14 I will ascend above the heights of the clouds; I will be like the most High.
Isa 14:13 For thou hast said in thine heart, I will ascend into heaven,
In Hebrew the word "ascend" is "alah", pronounced the same as "Allah". Notice that Lucifer is saying "I will ALAH my throne above the stars of God...I will be like the most High.
The "stars of God" would be the other angels, and here Lucifer is saying he is going to be equal or greater than God.
Educate yourself about who the god of Islam is and where he comes from historically:
The Spirit of Moloch
Islam's Curious God
Satanic Islam - The Bible, God's Holy Word clearly says that "by their fruits you will know them." And this is talking about those that say they are Christians, this can apply to anything. So when you look at the fruits of Islam, there can be no doubt about who the god is that millions around the world are worshipping every day.
If you don't realize just how dangerous Islam is, then you really do have your head buried.
There is NO WAY that Christianity and Islam can be joined together because that's elevating Satan to sit in God's throne. God is God and His glory will go to no one else.
