This book sheds new light on the history of the sanctity of Jerusalem in Islam. It is noticed already in the Quran which describes Muhammad's vision of a nocturnal journey from the "sacred mosque" (al-masjid al-ḥarām) in Mecca to the "far-off mosque" (al-masjid al-aqṣā) namely, the Temple Mount in Jerusalem. In his night journey to the site of the demolished Temple, Muhammad signaled to his contemporary Jews the course of salvation in which already Moses had led the Children of Israel to their promised land. On the other hand, the Quran praises also the Abrahamic sanctity of Mecca, especially in sūras which reflect the polemical rift with the Jews who eventually refused to recognize Muhammad as their messianic savior. After the death of Muhammad, when the first Muslims came from Arabia to Palestine, their awareness of the Quranic sanctity of al-Masjid al-Aqṣā resurfaced. This book elucidates major aspects of the renewed and growing sanctity of Jerusalem and al-Sham at large, as reflected in the available Islamic traditions. These traditions show also how patterns of the sanctity of Jerusalem were eventually adapted to Mecca in reaction to the growing prestige of Jerusalem, especially during the Umayyad period.
