Amin al-Islam Fadl ibn Hasan Tabarsi, is a scientist from the sixth century H. Since the long life time is regarded not only in the Qur’an, such as the life of Noah and Jesus, and since historians, have mentioned historically long-lived people, so the mentioned scientist reckons longevity as an ordinary subject and that, it isn’t considered something extraordinary and it is believed that an extension of time, doesn’t exclude life.
In addition to his citation on the past two reasons, he is holding fast to the divine powers and writes:
Now, it is proved that God, would contribute some people, among prophets and others, longevity, and this action, wouldn’t be contrary to God’s power and wisdom, so, why the long life of Imam Zaman may be denied, especially that, he is a proof of God’s servants and caliph of God on earth!
Yes, the God who has given to Noah and Elias, and Jesus a long life, he is also able to give Imam Zaman a long life. This scientist then, considers the matter, longevity, as a miracle because the prophets and Imams possess miraculous powers (12) and may take advantage of it, as a matter of survival. (13)
1- Nasir Toosi
Nasir al-Din Tusi (597- 672 H) in examining the question of the longevity has made advantage of two reasons:
First, because he is holding fast to God’s power and knowledge, He says that: some who believing that God is able and wisdom, the problem of long life, would not be impossible for him.
Then, he makes use of (historical experience) reason and names some people who had a long life and are living at the moment, people like :
Khedr and Elias (from Prophets) and the antichrist and Samaritan (from atrocities).
He wrote the results of discussion as:
Now that in both sides of this issue, i.e. the prophets of God and the enemies of God, it is permissible to have a long life, why in the middle i.e. god’s popular creations, longevity is not allowed! (14)
2- Scholar Erbeli
Scholar AAli ‘bn Isa Erbeli (death 693 H) reckons at longevity as an usual phenomena and in order to prove it , firstly refers to holy Quran which confirms longevity for prophet Noah.
Then, he has adopted some narratives which according to them, Elias has the longest life among the sons of Adam. He, then, refers to the history and mentions a large number of persons with a long life who lived prior or contemporary with the Islam Prophet sa Vslm in the Arab and non-Arab.
After that, he is holding fast to God’s power, and says that longevity of Hazrat Mahdi (P) in the light of divine power is completely, possible and practical. (15)
It is noteworthy that Arbly researcher. In discussing life, is largely influenced by Amin al-Fadl ibn Hasan Tabarsi
3- Ibn Maytham Bahrani
Kamal al-Din Maytham bin Ali bin Maytham Bahrani (699-636 AH. S), believes on Mahdi longevity subject as a improbability instead of a bug and in order to eliminate the improbability, grasps on three reason:
He firstly cites (historical experience) and with reference to aged News, The Life of Hazrat Mahdi (P) and even longer life is reckoned ordinary. Then, referring to the Quran he mentions the nine hundred and fifty-year-old resident of Noah among his people. Then he refers to sunnah and mentions St. Elias and Elias, the Antichrist and Samaritan. The life of these two Prophets , the Antichrist and Samaratin life is approved by both Shia and Sunni (fryqyn).
Hasan ibn Yusuf ibn Motahar, aka The Allama Hilli (726-648 H), is of great Shia scholars in the eighth century H.(17)
The mentioned scientist, believes that the question of the life of Hazrat Mahdi (P) is not a bug, but an improbability and of course a poor.
In order to fix improbability, he presented two reasons:
First, the possibility of long life, is undoubtedly granted.
Second, long lifetime, was happened in the past history. (18)
