dear JD...
the koran denies the Fatherhood of God and the Sonship of Jesus. (Therefore the bible accuses the koran) The idea of Jesus Christ, the Messiah, coming to redeem mankind by the shedding of His blood to be a propitiation for sins is foreign to the koranic text. (Therefore denying the entire NT premise of "Christ")
The koran denies that Jesus was crucified...
"That they said (in boast), "We killed Christ Jesus the son of Mary, the messanger of Allah"; but they killed him not, nor crucified him. Only the likeness of that was shown to them. And those who differ therein are full of doubts, with no (certain) knowledge. But only conjecture to follow, for a surety they killed him not-nay, Allah raised him up unto himself; Allah is exalted in power, wise." Surah 4:157
yes, there are isolated texts in the koran that do seem to agree with the bible but these same texts can also be contradicted by other individual koranic texts as well as when the whole corpus of the koran is considered. That is why many people have found that a study of the koran proves that it isn't in harmony with the bible. If you were to read some of the hadiths they go into the details of how the jewish rabbis rejected mohammad's claim to prophethood and then he turned on the jewish people all together for this slight. The hadiths are very important to the story of the rise of islam. They put the actual sayings of the koran in context. Otherwise there is rambling with no reason. The koran and the hadith are seen as a two edged sword, where the bible alone stands sharper than a two edged sword.
Incidentally, that is WHY the bible alone can condemn the two edged sword of the mormons which is the bible + the book of mormon AND the WTBTS bible + their unique doctrines expoused in the pages of their other books.

p.s. still not sure why you defend the koran. Is it simply because you can't see any contradiction to the bible?
