However...
However, this objection is not acceptable since acceptance if this criterion does not require certitude concerning the existence of eternal life and the mere fact that it may exist would suffice, and no doubt logically speaking such possibility exist. The possibility mentioned above exist since, firstly no irrefutable proof or convincing reason denying God existence, the next world or other spiritual matter has been set forth.
Therefore, we cannot be certain of the non-existence of these things and the negation of the certainty of their non- existence would lead to the possibility of their existence. Secondly this is not a week possibility, for history shows that even those who denied the prophet admitted that in their behaviour,intelligence, andunderstanding of the truth they were far ahead of their time.
Thus those who have no faith in the divinely revealed religions and the prophets still cannot deny the truthfulness and intelligence of this prophet s.
Moreover the holy scripture and the history of religion show that all prophet, from Adam, peace be upon him, to Mohammed, the seal of the prophet, peace be upon him and his household, without exception have informed the people of the existence of God and his oneness, the existence of the next world, the different degrees of closeness to, or remoteness from God and paradise and hell.
Moreover many mystics from different nation and sects throughout history have borne witness to some of these things. To a sound intellect his great volume of evidence greatly increases the probability that such things do indeed exist.
The reason tat for the acceptance of that criterion the mere probability of the existence of these things is enough is that firstly from a logical perspective not only preventing a definite harm is necessary but so is a avoiding a probable one That is if someone thinks that there is a chance he be exposed to certain harm and avoiding that harm would not entail similar or greater harm, reason dictates that he should aroid that harm.
According to the Quranic verse , Prophetic tradition and the teaching of other holy scripture, the intentional denial of the spiritual truths mentioned above and disbelieving them will incur internal punishment the mildest of which is incomparably this world. The same dire consequence is also in store for those who neglect issue concerning the hereafter.
