“When the Imam Mahdi calls out, he will supplicate to God in Hebrew.” [Al-Ghaybaa of an Numani, p.326]
In Hebrew. The Jews will dance with joy, insha’ Allah, according to the hadith.
“THERE WILL BE A PEOPLE FROM THE TRIBE OF MOSES (AS)... ALONGSIDE HAZRAT MAHDI (AS).” [Sheikh al-Mufid, Kitab al-Irshad, p. 402]
Maybe the top names from the Sanhedrin court, and many religious Jews will support Hazrat Mahdi (as). Who says this? The Prophet Mohammed (saas) says this.
Prophet Mohammed (saas) says “We have Al Jafr. Do they not know what Al Jafr is? So, I asked. What is in Al Jafr? The scholars of the prophets and those who achieved their hopes and the knowledge about the past Israeli scholars.”
Hazrat Mahdi (as) will work out this knowledge from the Torah, from the unaltered parts of the Torah. So we understand that Hazrat Mahdi (as) will announce the information about the Messiah, Hazrat Mahdi (as).
“When Mohammed Mahdi Qaim, from the family of the Prophet Mohammed (saas) appears, he will rule according to the sharia of David and Solomon.”
What does it mean? He will act like Prophet David (as) in the Qur'an, like Prophet Solomon (as) in the Qur'an. Indeed, another name of his is the son of David. He is mentioned as the son of David in the Torah. Hazrat Mahdi (as) will be a descendant of Prophet David (as). “He will rule according to the sharia of David and Solomon.” In other words, he will be similar in terms of the character, soul, belief and understanding of Prophet David (as) and Prophet Solomon (as) according to the Qur'an.
“The world will not come to an end until a member of my family appears and rules according to the rules of the family of David.” Prophet Mohammed (saas) says, Hazrat Mahdi (as) will spread justice just like Prophet David (as). How? He will refer to the Qur'an to do that, insha’ Allah.
Imam Ali (ra), in his famous diwan, mentioned Hazrat Mahdi (as) and some of the things that will happen in the End of Times. Some of it reads as follows:
Translation: “My son! When the Turks rise, be ready to see Mahdî-i Âdil. His name is similar to Mohammed’s ancestors’ name, let my soul be his.” Meaning, for Allah’s pleasure, I would have sacrificed myself for him. Know that he is the one. Be sure that Hazrat Mahdi (as) is the one that will guide. Do not take him as an unimportant man and rush to his side. Go quickly and swear allegiance to him. He shares a name with Mohammed (saas)’s ancestors’. In other words, B’nei Adnan. Hz. Ali (ra) says this in his diwan. What is the lineage of Prophet Mohammed (saas)? B’nei Adnan. He shares a name with B’nei Adnan. In other words, when the Prophet Mohammed (saas) said his name is equivalent to my name, and his father is equivalent to my father’s name, he meant this and Hz. Ali (ra) explains it. Indeed, Hz. Ali (ra) calls the Prophet Mohammed (saas), Mustafa Adnan Prophet in his eulogy. The Prophet Mohammed’s (saas) name was Mustafa and his surname was Adnan.
