Allah wants to convey the idea that Allah knows that if Muhammad Al-Mustafa (S) left this world without reforming the bad elements of the society, no prophet was to come after him to fill that gap; and if Muhammad Al-Mustafa (S) without giving effect to all the reforms of the society, no such person was ever to appear who would have such respect, prestige and reverence among the masses that his every word and his every action would have the force of Law.

It was the prerogative of the Holy Prophet of Islam; and nobody had, or was to have, such respect that if he did one thing it became lawful for up to Qiyamah (Resurrection day), and if he forbade one thing, that became unlawful for up to Qiyamah. This prestige was bestowed by Allah upon the Last Prophet and Allah knew that if he did not reform such bad customs no other person would ever be able to give effect to such reforms after the Holy Prophet.

Looking at this verse in this context, it is crystal clear that we cannot accept a new meaning to this verse invented by a homemade claimant of prophethood from Qadian, that 'Khatam un-Nabiyyin' means 'Seal of the prophets" which in its turn means that the prophets coming after the Holy Prophet of Islam would become prophet by the seal of the seal of the Holy Prophet, and by his confirmation. If we were to entertain such idea, all the force and logic will be wiped out.

Not only that it will lose its logic - it will be tantamount to refuting whatever was put forward in the preceding phrases and sentences. This verse will become a self-contradictory statement. How? We have seen that Allah wanted to reply to the objections of the enemies of the Holy Prophet, by saying that: The Holy Prophet married Ummul-Mumineen Zainab bint Jahash by order of Allah.

The aim of that marriage was to remove the prejudice and superstition and traditional taboo of the pagan Arabs and many other nations who treated the adopted sons as the real sons. It was necessary, nay essential for Muhammad Al-Mustafa (S) to marry the divorced wife of his adopted son, so that Muslims should not feel shy of such marriages; they should be persuaded by the practical example of the Holy Prophet that such marriages are perfectly lawful, because an adopted son is no son at all.

To show the urgency of those marriages, Allah says that Muhammad Al-Mustafa (S) is the Messenger of Allah and it was Imperative for him to give effect to that marriage to provide a practical example.
