AbdAlRahman, please note that the Christianity board is for discussions about Christianity - and whilse there's nothing wrong with sincere questions about Christianity, the sort of question being here seems to have an undercurrent of trying to evangelise for Islam.
If Christianity held predictions about the coming of Mohammed, you can be assured that many Christians would have become Muslims by now - the fact that Christians don't believe Mohammed to extend from their own tradition, nor did Mohammed claim to be the second coming of Christ, suggests that perhaps there is going to be very little cross-over agreement between Christians and Muslims as to the role of Mohammed in relation to Christianity.
