All three Abrahamic faiths have agreed, since the time of the crusades, that there should be a House of Worship on the Temple Mount, dedicated to the God of Abraham. Thats what the mosque is. It all started with prophet Abraham attempting to sacrific his son on that hill. Thats why they housed the Holy of Holies there. Thats why king David built a temple there. Thats why Christians built a church there. And thats why there is a mosque there.
