Surah 17. Al-Israa, Ayah 108

This may be an allusion to the many Biblical predictions of the advent of the Prophet Muhammad, especially to Deuteronomy xviii, 15 and 18 (cf. surah {2}, note [33]). In its wider sense, however, the "fulfilment of God's promise" relates to His bestowal of a definitive revelation, the Qur'an, henceforth destined to guide man at all stages of his spiritual, cultural and social development.

Those who had received previous revelations find in the Qur-an and in the Messenger who brought it, the promise of Allah fulfilled. Those who were spiritually prepared for it found in the same way the satisfaction of their spiritual yearnings: to them, also, Allah's promise was sent to be fulfilled.
