In the absence of any one of the above two eventualities, the mere appointment of a past Head of State to a State duty does not change the constitutional position. The same applies to the second advent of Christ, son of Mary. The seal of Prophethood is not violated by his second advent.
However, if he assumes the office of Prophethood once more and starts performing the duties of a Prophet or conversely a man repudiates the sanctity of Christ (PBUH) as a former Prophet, both these cases constitute a violation of God's law in respect of the creation of Prophets. The traditions have clearly ruled out the existence of both these possibilities. On the one hand, the traditions affirm that no Prophet shall come after Muhammad (PBUH).
At the same time, they foretell the second coming of Christ, son of Mary. This is sufficient to make it clear that during his second advent in the world, Christ will not discharge the duties of a Prophet. In the same manner, his advent will not give rise to a new question of faith or apostasy among the followers of Islam. Any one who repudiates the sanctity of Christ as a former Prophet is an apostate. The Holy Prophet (PBUH) himself affirmed Christ's sanctity as a former Prophet.
The followers of Muhammad (PBUH) therefore, have from the beginning, always believed in the sanctity of Christ as a former Prophet. This belief will hold good even at the time of the second advent of Christ. At that time Muslims will not put faith in the ministry of a new Prophet. They will retain their belief in the sanctity of Christ as a former Prophet.
This position is neither contrary to faith in the Finality of Prophethood today nor will it be derogatory to this belief at the time of Christ's second advent in the world.
The last point which is made clear by these other traditions and numerous others pertains to the fact that Dajjal (for the suppression of whose grave misdeeds God will send Christ, son of Mary(peace be on him), will arise among the nation of Jews and that he will impose as 'Masih.' No one can understand the reality of this fact without studying the history of the Jews and their religious beliefs. After the death of Hadrat Sulaiman (PBUH) [i.e.
Solomon], the tribe of Israel suffered perpetual decline until it came to pass that they became slaves of the Babylonian and Assyrian Empires and their imperial masters dispersed them over the face of the earth.
