The first passage that mentions imam Mahdi AJ is psalms 72. The passage is too long so I linked it. Jews believe it’s about prophet Solomon AS, however there’s a verse which only applies to imam Mahdi AJ without the previous kings of Israel which is:
5 May he endure as long as the sun as long as the moon, through all generations
And it is important to mention that “the king” here is not prophet David AS rather it is prophet Muhammad SAWA since Imam mahdi AJ is “king’s son”.
Here’s a Quranic verse to support this claim:
We wrote in the Psalms after the Remembrance (al thikr) that the earth will be inherited by My righteous servants. 21:105
The second passage can be found in Zechariah 9. And it is
9 Rejoice greatly, Daughter Zion!(P) Shout,(Q) Daughter Jerusalem! See, your king comes to you,(R) righteous and victorious,(
10 He will proclaim peace(W) to the nations. His rule will extend from sea to sea and from the River[b] to the ends of the earth.(X)
For some reason mukhalifeen think this is about umar ibn al khattab even though umar never ruled “to the ends of the earth”
Idk I’m guessing Ka’b al ahbar LA didn’t interpret well this time
Jesse is the father of prophet David AS. However the root between imam Mahdi AJ and Jesse could be through his mother syeda Narjis SA, which she is from the progeny of Simon Peter AS. And perhaps Simon AS is from the progeny of Jesse or David AS
3 and he will delight in the fear(I) of the Lord. He will not judge by what he sees with his eyes,(J) or decide by what he hears with his ears;(K) 4 but with righteousness(L) he will judge the needy,(M) with justice(N) he will give decisions for the poor(O) of the earth.
The highlighted part proves imam Mahdi AJ will rule by ilm al ghayb
12 He will raise a banner(AU) for the nations and gather(AV) the exiles of Israel;(AW) he will assemble the scattered people(AX) of Judah from the four quarters of the earth.(AY)
Abu Abdullah as-Sadiq (as) had said about this verse, “…therefore hasten to (do) good works; wherever you are, Allah will bring you all together:” “It has been revealed about al-Qa’im (as) and his companions. They will meet together without an appointment.”
7 “Awake, sword, against my shepherd, against the man who is close to me!” declares the Lord Almighty. “Strike the shepherd, and the sheep will be scattered, and I will turn my hand against the little ones.
The shepherd may refer to either Iblis LA, Dajjal LA, or al Sufyani LA; and the sheep are their followers
8 In the whole land,” declares the Lord, “two-thirds will be struck down and perish; yet one-third will be left in it.
from Muhammad bin Muslim and Abu Basir that he said: We heard Abi Abdullah (a.s) say: “It will not take place till two-third of the human population does not perish.” He was asked: “If two-third perishes, who will remain?” He replied: “Are you not satisfied that one-third will remain?”
9 This third I will put into the fire; I will refine them like silver and test them like gold.
Do not rejoice in wealth and prosperity, and do not be saddened by poverty and affliction, for gold is tested by fire, and the believer is tested by affliction (3).
They will call on my name and I will answer them; I will say, ‘They are my people,’ and they will say, ‘The Lord is our God.’”
Excerpt from Hadith al Lawh:
They are truly My friends. I will fend off all oppressive seditions by them. I will fend off any earthquakes by them. I will eliminate any hardships and burdens by them. They are the ones on whom is the Blessings and Mercy from their Lord. They are the guided ones.’”
