Foundations and Purposes of Imam Mahdi’s (a) Global Governmen
My Lord would have not concerned Himself with you if it were not for your call (upon Him). (25:77)"
There are sayings from the Imams (AS) that show Allah may cancel a decisive/confirmed decree (Qadhaa al-Mubram) regarding a worldly punishment that is about to take place, just due to the Du'aa of His servant. It is narrated:
Imam Musa al-Kadhim (AS) said, "I advise you to Du'aa. Certainly Du'aa and request from Allah, the Mighty and the Majestic, drives away an affliction that was planned, was passed, and all that was remaining was its execution (Imdhaa). When Allah is implored, He averts the affliction an amazing averting."
As we have seen, there are massive pieces of evidence in the Quran that clearly disprove the doctrine that states "the Pen has dried up for all future events". In contrast, the followers of Ahl al-Bait (AS) do not emulate the Jews who considered Allah had concluded the matter. We believe Allah's hands are open to do as He wills and chooses. Nevertheless, Allah does not act without purpose. The changes in decree have educational purposes for people including the Prophets and the Imams, peace be upon them. Although people are usually unaware of the details of all such changes, yet by realizing the general concept of al-Badaa, one will truly understand that everything is in the hand of Allah and He is able to do all things at any time, and that it is never too late for Him to do anything He wills. It demonstrates the absolute freedom of Allah in all His actions and that He is never restricted by His own creations, including His previous will. Moreover, it removes the suspicion of compulsion and non-revocable pre-destination, and gives the sinners hope that Allah may totally revive their past and future. It encourages them to strive hard, to implore Allah, and to act upon good deeds with the hope that Allah may fix their deeds and may change their fate. Zurara Ibn A'ayun and Hisham Ibn Salim narrated:
Imam al-Sadiq (AS) said, "Allah was not worshipped to the extent that He was worshipped due to al-Badaa. Allah was not glorified as much as He was glorified due to al-Badaa."
The sudden nature of the advent of al-Qa'im (AS)
The Shia and the Sunni traditionalists have narrated that the advent of Imam al-Mahdi (AS) will be rectified by Allah within just one night. In other words, its time is very unpredictable and depends on Allah's sudden choice of action and his advent will take place miraculously. The Sunnis have narrated from Muhammad Ibn Hanafiyya (RA) and Imam Ali (AS) that the Holy Prophet (PBUH&HF) said:
"al-Mahdi is of us Ahl al-Bait (AS); no doubt, Allah will rectify his matter within a night."
In some other traditions, the Imams (AS) stated that the time of the rising of al-Qa'im (AS) is like the time of the Hour of resurrection, which is completely unpredictable and is known only by Allah. The time of resurrection has not yet been decreed and Allah shall enforce it suddenly once He wills. Di'bil narrated:
Imam Ali Ibn Musa al-Ridha (AS) said, "The Imam after me is my son, Muhammad (AS), and after him is his son Ali (AS), and after Ali is his son al-Hasan (AS), and after al-Hasan is his son the Proof of Allah who shall stand (al-Hujjat al-Qa'im). He is awaited during his occultation and is obeyed during his manifestation. Even if there remains from the life of the world but a single day, Allah shall expand that day until he rises and fills the world with justice in the same way that it was filled with tyranny and injustice. But when? As for news of the time (of reappearance), indeed my father told me having heard it from his father who heard it from his ancestors who heard it from Ali (AS) that it was asked from the Prophet (PBUH&HF), 'O the Apostle of Allah! When will al-Qa'im from your offspring appear? He said, 'His similitude is the similitude of the Hour (of resurrection). None but He shall manifest it at its time. It is heavy for the heavens and the earth. It will not come to you unless suddenly. (7:187)'"
