THE MAIN theme of this surah - which according to the 'Itqan belongs to the last group of the Meccan revelations - is the stress on the oneness, uniqueness and transcendence of God and on the fact that this truth has always been the core of all prophetic revelation, "the essence of all that you ought to bear in mind" (verse 10), and which man only too often forgets: for "the deaf [of heart] will not hearken to this call, however often they are warned" (verse 45), and "but listen to it with playful amusement, their hearts set on passing delights" (verses 2-3). The repeated allusions to some of the prophets of old, all of whom preached the same fundamental truth, provide the title of this surah. The stories of those prophets are meant to illustrate the continuity and intrinsic unity of all divine revelation and of man's religious experience: hence, addressing all who believe in Him. God says, "Verily, this community of yours is one single community, since I am the Sustainer of you all" (verse 92), thus postulating the brotherhood of all true believers, whatever their outward designation, as a logical corollary of their belief in Him - the belief that "your God is the One and Only God" (verse 108).
