What is the relationship between Imam al-Hussain's movement and the global movement of Imam al-Mahdi?

These two infallible Imams are the real successors of Prophet Muhammad so, they pursue a common divine policy and their movements are to implement the glorious goals of all the prophets and their successors. Regarding this, the most important common goals between these two divine leaders are to stand against the oppression and social corruptions and to prepare the ground for applying justice.

Imam al-Hussain remarked his goals when he left Medina for the last time by saying:

«أَنِّي لَمْ أَخْرُجْ أَشِراً وَ لَا بَطِراً وَ لَا مُفْسِداً وَ لَا ظَالِماً وَ إِنَّمَا خَرَجْتُ لِطَلَبِ الْإِصْلَاحِ فِي أُمَّةِ جَدِّي أُرِيدُ أَنْ آمُرَ بِالْمَعْرُوفِ وَ أَنْهَى عَنِ الْمُنْكَرِ وَ أَسِيرَ بِسِيرَةِ جَدِّي وَ أَبِي‏ عَلِيِّ بْنِ أَبِي طَالِبٍ»[1]

"I do not arise (against Yazīd) for a sole desire or as an insolent, corruptive, or tyrant person. I have arisen (against Yazīd) seeking to apply amendment in the Ummah of my grandfather. I wish to enjoin the good and forbid the evil, and act according to the path of my grandfather and my father, Ali bin Abī Tālib…"

Also pertaining to accomplishing the divine mission of Imam al-Mahdi, Imam al-Hussain says,

«لَوْ لَمْ‏ يَبْقَ‏ مِنَ‏ الدُّنْيَا إِلَّا يَوْمٌ‏ وَاحِدٌ لَطَوَّلَ اللَّهُ عَزَّ وَ جَلَّ ذَلِكَ الْيَوْمَ حَتَّى يَخْرُجَ رَجُلٌ‏ مِنْ‏ وُلْدِي‏ فَيَمْلَأَهَا عَدْلًا وَ قِسْطاً كَمَا مُلِئَتْ جَوْراً وَ ظُلْماً كَذَلِكَ سَمِعْتُ رَسُولَ اللَّهِ يَقُول‏»[2]

 “Even if there should not remain, but a single day from the world, Allah, the Exalted, the Glorified, will prolong that day so much that a man from my progeny arises. He will fill the earth with justice and equity as it will be replete with injustice and oppression. This is what I heard from the messenger of Allah”.

Consequently, the most important achievement that Imam al-Hussain wanted to gain will exist in the global governance of Imam al-Mahdi as well. In his government, the aims of the previous prophets and their successors will be actualized and people will taste the real meaning of justice, safety and salvation.
