During these days, among the Quraish there were some who attempted to console their hearts by the idea that Muḥammad[sa] is without heir and without progeny, and in a few days time his succession shall finish by itself. Upon this it was revealed that:
Meaning, “O Muḥammad[sa]! We have made thy progeny, and thy blessings and thy munificence long lasting. Therefore, spend freely, the powers of thy being, and thy progeny, and thy wealth, for these treasures shall not come to an end. However, the progenies of thy ill-wishing enemies shall be erased.”1
The glory in which this revelation was fulfilled in favour of the Holy Prophetsa, and the horror in which it was fulfilled for his enemies, is like an open page of history which requires no elaboration. The children of this very opposition entered the fold of Islām, and put a seal on the fact that not only the Quraish, rather, among all the tribes of Arabia, if there was anyone whose progeny remained, it was that of Muḥammadsa the Messenger of Allāh.
