He will fill it with justice and equity just as before him...
He will fill it with justice and equity just as before him it was filled with tyranny and oppression. He is my fifth descendant. He will be in occultation for a long period due to the fear of his life. In that period, many will become deviated from religion. Praised are our followers who remain steadfast on our mastership, are firm on our friendship and on the enmity of our enemies in the period of Qa’im’s occultation. These are from us and we are from them.
They are satisfied with our leadership and we are satisfied with them as our followers. Thus congratulations are due to them as Allah will place them with us on the Day of Judgment.”[^9] Imam ‘Ali ar-Ridha’ (a.s.) said: “When our Qa’im reappears, he will appear like a youth. His strength will be such that if he extends his hand towards the biggest tree it will be uprooted. The mountains will break up on his pleadings.
He will have the staff of Hazrat Musa (a.s.) and the ring of Hazrat Sulaiman (a.s.). He is my fourth descendant. Whomsoever and howsoever Allah wishes, He will conceal him from the eyes of the people. When the Qa’im reappears, he will fill the earth with justice and equity just as previously it was filled with oppression.”[^10] Imam Muhammad Taqi al-Jawad (a.s.) said: “Qa’im is our Mahdi, who will guide (the people).
It is necessary upon everyone to wait for him in his occultation and obey him when he reappears. By Allah Who raised Hazrat Muhammad Mustafa (s.a.w.a.) for Prophethood and selected us for Imamat, even if a single day remains from the life of this world, Allah will lengthen it to such an extent that our Qa’im reappears and fills the earth with justice when it would be filled with tyranny and oppression.”[^11] Abdul Azim Hasani asked Imam ‘Ali Naqi al-Hadi (a.s.): “Who will be my master after you?
Imam (a.s.) replied: “After me, it is my son Hasan. But what will be the condition of the people after him?” On being asked to explain his concern, he (a.s.) further reasoned: “As nobody has seen him and it is prohibited to take his name till he reappears and fills the earth with justice just as it was previously filled with tyranny and oppression.”[^12] Imam Hasan al-Askari (a.s.) said: “I can foresee your dispute about my successor after me.
Beware that if a person believes in Imamat and the past Prophets (a.s.) but denies my son, then his example is as if he believes in all Prophets but denies the Prophethood of Hazrat Muhammad Mustafa (s.a.w.a.).
