Among all the people, His Eminence is most resembling His great grandfather, the Messenger of Allah (a.s), by way of method, Jihad and revolution against oppression and transgression and transformation of the system of the oppressive rulers in society, from theft and destruction humiliation, affliction and problems. He would replace all this with a system that would provide every kind of comfort and security and be a cause of general welfare and happiness of the people. When the Qaim of the progeny of Muhammad would appear, he would work in the same way as his great grandfather had done. That is why he would destroy the false powers and tyrannical rulers whose power is based on falsehood and hypocrisy and he shall eradicate them completely. He would then establish justice and equity in every sense of the term.
Numerous traditions of the Holy Prophet (a.s) and the Imams of guidance have reached us that mention that Imam Mahdi (a.s) resembles his great grandfather, the Messenger of Allah (a.s). Some of them are mentioned below:
1. Abdullah Ibne Masud narrates from the Messenger of Allah that he said, “A man from my family would arise having my name, and his manners and habits would be like my manners and habits and he would make the earth abound with justice and equity.”
2. Huzaifah relates from the Messenger of Allah (a.s) that he said:
“Even if there remains one day in the life of the earth, God will bring forth a man whose name and character will be like mine, and whose patronymic will be Abu Abdillah. People would pay allegiance to him between the Rukn and Maqam of Ka’ba. Through him God will revive His religion and bring it back to its early glory. God will also endow him with many victories and there will remain on earth none other than the ones who will declare: There is no god, except Allah.”
Sulaiman got up from his place and asked as to which of his children’s descendent he would be.
The Prophet struck his hand on Husain (a.s) and said, “From his [descendants].”
3. Ayesha has narrated from the Messenger of Allah (a.s) that he said:
“Mahdi is a person from my progeny. He will fight for my Sunnah like I have fought for revelation.”
4. Jabir Ibne Abdullah Ansari has quoted the Messenger of Allah (a.s) that he said:
“The Mahdi is from my progeny, his name and patronymic is same as mine. Among all the people he would resemble my character. There would be an occultation for him during which people shall be perplexed. After that he would reappear like a bright star and make the earth abound with justice and equity after it had been completely fraught with injustice and oppression.”
5. Imam Ja’far Sadiq (a.s) has narrated through his forefathers from the Messenger of Allah (a.s) that he said:
“The Mahdi shall be from my descendants. He would be having the same name and agnomen as I have. He would resemble me most in character; he would have an occultation which would cast people into confusion, till they deviate from their religion. At the time he reappears he shall be like a brilliant star. Then he would spread justice and equity on the earth just as it would have been absolutely fraught with injustice and inequity.”
6. Imam Ja’far as-Sadiq (a.s) has narrated through his blessed ancestors from the Holy Prophet (a.s) that he said:
“The Qaim is from my descendents. His name is same as mine and patronymic is same as mine. His appearance is like my appearance and his practice like my practice. He will establish the people on my religion and my law and call them to the Book of my Lord, the Mighty and the sublime. One who obeys him has obeyed me and one who disobeys him has disobeyed me. And one who denies his occultation has denied me. And one who falsifies him has falsified me. And one who testifies for him has testified for me. I would complain to Allah about those who falsify me in my affair and those who mislead the people. And the oppressors would soon realize where they would be returned when they are sent back (to Hell).”
The above tradition is the most comprehensive one that shows that Imam Mahdi (a.s) would be like his great grandfather, the Messenger of Allah (a.s) in many respects.
7. Abu Salih Saibi in Al-Fitan has narrated from His Eminence, Amirul Momineen (a.s) that he said: “His Eminence, Mahdi (a.s), in appearance, character, habits and good virtues, would most resemble the Messenger of Allah (a.s).”
Such types of traditions have reached us in large numbers from the Holy Prophet (a.s) and the Holy Imams (a.s). They all prove beyond any doubt that Imam Mahdi (a.s) not only resembles the Holy Prophet (a.s) in appearance and built; he is also having the same type of character and habits, due to which he is more superior to the other prophets of God. Rather in his method of reformation, engagements and his war tactics for the annihilation of oppression and injustice and for the establishment of equity and justice on the earth he closely resembles his great grandfather, the Messenger of Allah (a.s).
