He will not be the bearer of any new message or repository...
He will not be the bearer of any new message or repository of a fresh mandate from God, nor will he amend, enlarge or, abridge the Shariah of Muhammad (PBUH), nor indeed will Christ son of Mary be brought into the world to accomplish the renewal of faith. Christ son of Mary (PBUH) will not call upon the people to put their faith in his own prophethood, nor will he found a separate community of followers[see footnote 12].
He will be appointed to accomplish a particular task and this will be to root out the mischief of Dajjal. To serve this purpose, Jesus(PBUH) will descend in such manner that those Muslims among whom he appears, will have no doubt at all about his identity as Jesus son of Mary whose advent at a most opportune time was foretold by the (PBUH). Jesus(PBUH) will join the community of Muslims and will offer prayers behind the incumbent Imam of the Muslims[see footnote 13].
He will allow the incumbent Imam of the Muslims to supersede him so as to make it clear beyond any shadow of doubt that he has not descended to assert his position as a Prophet or to carry out the office of Prophethood. There is no doubt that in the presence of a Prophet among a community of people no other person can assume the office of an Imam or a leader.
Hence when Jesus(PBUH) will become an individual member of the Fraternity of Islam, this fact will in itself proclaim to the world that he has not descended to assume the office of a Prophet. On this basis, therefore, the question of opening the seal of Prophethood at the second coming of Christ is completely irrelevant.
It might be said (without actually comparing the two situations) that Jesus's advent will be like the appointment of a former Head of State to render some State service under the regime of the present Head of State. It is not too difficult for a man of ordinary common sense to understand that the appointment of a former Head of State to render some State duty under the regime of present Head is not a violation of the constitution of the State. Two cases, however, do violate the State Law.
In the first case, if a former Head of State makes a bid to assume that office once again. In the second case, if a person refutes the existence of the former regime of a defunct Head of State, for this would be tantamount to challenging the validity of the tasks carried out by the former regime.
