Ghaibat Tusi: Kulaini has narrated from Imam Hasan Askari (a.s.) that:
“When Imam Zaman (a.s.) was born, he said: The oppressors assumed that they will kill me in order to discontinue this succession. How did they see the might of Allah!”
He named him Muammal (the one in whom hopes rest). 1
Ghaibat Tusi: It is narrated from Fadhl from Musa bin Sadan from Abdullah bin Qasim Hadhrami from Abi Saeed Khurasani that he said:
I asked Imam Ja’far Sadiq (a.s.), “Is the Mahdi and the Qaim the same?”
He said: “Yes.”
I asked, “For what reason has he been named the Mahdi?”
He said: “Because he will be guided to every hidden matter. And he is named Qaim, because he will rise after his name dies. He will establish a mighty enterprise.” 1
Irshad: Muhammad bin Ajlan narrates from Imam Ja’far Sadiq (a.s.) that he said:
“When the Qaim rises, he will call people to Islam anew and will guide them to an order that is worn out and the masses have been led astray from it.
The Qaim has been named the Mahdi, because he will lead to an order that is led astray from and he is named Qaim for his rise with the Truth.” 1
Tafsir Furat: Ja’far bin Muhammad Fazari has narrated from Imam Muhammad Baqir (a.s.) in reference to the Divine words:
فَقَدْ جَعَلْنَا لِوَلِيِّهِ سُلْطَانًا فَلَا يُسْرِفْ فِي الْقَتْلِ ۖ إِنَّهُ كَانَ مَنْصُورًا
“We have indeed given to his heir authority, so let him not exceed the just limits in slaying; surely he is aided.” (Surah Isra 17:33)
…he said: “This is Husain.” So he may not exceed in killing and he is Mansur (helped, assisted, and aided), the Imam said: “Allah has named the Mahdi, al-Mansur as He has named Ahmad, Muhammad, and Mahmud, and as He has named Isa Masih.” 1
Kashful Ghumma: Abil Khashab says: Narrated to me Muhammad bin Musa Tusi from Abdullah bin Muhammad from Qasim Ibne Uday that he said:
“It is said that the patronymic of Khalaf Salih (The Virtuous Heir) is Abul Qasim and he has two names.” 1
