Answer 2
The Islamic Caliphate only held together as one empire for 120 years (630 C.E. to 750 C.E.). This is less time than the United States was around and roughly the equivalent time of the worldwide British Empire (1830-1950). Therefore, it is not unrealistic or special that the Rightly-Guided Caliphate and its successor state the Umayyad Caliphate remained united. There was a strong intent to integrate the conquered populations and many in the territories wished to become Muslim due either to conviction or to financial incentive. When the Abbassids overthrew the Umayyads in the Middle East, the Islamic Empire broke up into numerous Caliphates and Sultanates (such as the Umayyads, Abbassids, Idrissids, Aghlabids), returning to the natural state of disunity. The Abbassid Caliphate would further break down into in the next two centuries into the Fatimid, Ayyubid, and Buyid Caliphates. The fact that the Ottomans became the spiritual successor State to the Rightly-Guided Caliphate by way of the Umayyads by way of the Abbassids by way of the Ayyubids by way of the Mamluks by way of the Seljuks, is purely incidental and only occurred because the central Middle East was consistently under the control of an Empire that was Islamic. These empires were held together by institutions such as the governates (wilayat), roads, and police/soldiers, just like every other empire. It just happens that track record of violence and repression is better for Islamic Empires.
