Ahle Tasannun scholar Ibrahim Hamveeni has mentioned in his book Faraaed al-Simtain, vol. 2, p. 335, a tradition from Imam Muhammad Baqir (peace be upon him) who narrates from his father Imam Zain al-Aabideen (a.s.) from his father Imam Husain (peace be upon him) from Ameerul Momineen (peace be upon him) who narrates that the Holy Prophet (peace be upon him and his holy progeny) said,
“Mahdi is from my progeny. There will be an occultation for him and perplexion in which nations will have deviated. He will reappear with the inheritance of prophets. And he will fill this earth with justice and equity just as it would have been filled with oppression and tyranny.”
It is clear from this tradition that Imam Mahdi (a.t.f.s.) will have an occultation in which people will have deviated. In other words, it will be very difficult for people to protect their faith during occultation. Another important point that has been mentioned in this tradition is that Imam Mahdi (a.t.f.s.) will reappear with the inheritance of Prophets (peace be upon them). Inheritance of Prophets means all those miracles through which they presented the proof of their authenticity. For example, the ring of Prophet Sulaiman (peace be upon him), the staff of Prophet Musa (peace be upon him), the casket of Bani Israel which was known as the casket of ‘Sakina’. Therefore, whoever desires to see the miracles of the past Prophets must excessively pray for the reappearance of Imam Mahdi (a.t.f.s.) since he is their rightful heir.
Lastly, we pray to Allah for the sake of all Prophets (peace be upon them) that may He reward them for all their efforts in this world and hasten the reappearance of Imam Mahdi (a.t.f.s.) so that he can fulfill the aim of the Prophets (peace be upon them).
Aameen, O Lord of the worlds!
