what is the meaning of name Gharim for promised saviour ?

The fifth is “Gharim”. The title is of The Excellency’s special titles, and it is one of his common titles in narrations.

Gharim can mean both a “Debtor” and a “Creditor”. Here, it looks to mean the first one. This tile was given to him because of Taqīyah, like the title Qulām [an adolescent boy]. As the Shiites used to send him or his Four Deputies, some money, write wills or borrow some [money] from him, they called him “Gharim”.

However, most of the farmers, traders, craftsmen and artisans owed money to the Imām (mgehr). Similarly, it was mentioned about what happened to Muḥammad ibn Sālih; one of Imām Haṣan ʻAskarī (pbuh)’s companions.

[In addition,] Allama Majlisī (Mgbh) said:

Gharim may mean “The Debtor1”. So, they have entitled The Excellency to it; because, he has been hiding himself [during the Occultation Eras]; due to being [spiritually] indebted to the people. If people see The Excellency, they will ask the Imam (mgehr) for his knowledge and the religious law. Therefore, he [necessarily] has to leave them; due to Taqīyah. Yes, The Excellency is an occulted debtor! May God hasten his emergence (14)!

The sixth is “Qā’im”. It means, the one whom the Almighty God will rise to obey God’s order. Yes, The Excellency has been prepared all days and nights, to put the divine order into action, as [God] orders him to emerge.

 

1-In the Major Occultation Era [now], Imām Mahdī (mgehr) are not to be seen by most people, except pious and pure ones. So, not all people can enjoy learning his knowledge and guidance. But after the Emergence, all will enjoy his presence.
