Imam Mohammed al-Baqir pbuh has clarified this matter:
And in the narration in the interpretation of Ali the son of Ibrahim that Abi Ja'afar (PBUH) said:" Verily, Jesus (PBUH) promised his disciples the night in which Allah raised him, so they all gathered by night time, and they are twelve men, so he made them enter a house then he came out to them from an eye in the corner of the house, and he was shaking his head from water, then he said, verily Allah is raising me to him this hour, and He is my purifier from the Jews, so who among you is to have my ghost thrown upon him that he may be killed and crucified and be with me in my status/level? So a young man from them said, I am, O spirit of Allah, so he said, so you are he". Then he (PBUH) said "Verily the Jews came in demand for Jesus (PBUH) from their night…and they took the young man whom the ghost of Jesus (PBUH) was thrown upon so he was killed and crucified)"

Gospel of Judah, Scene 3: [Judah said, “Master, could it be that my lineage is under the control of the rulers?” Jesus answered and said to him, “Come, that I [ … two lines missing … ], but that you will grieve much when you see the kingdom and all its generation.” When he heard this, Judah said to him, “What good is it that I have received it? For you have set me apart for that generation.” Jesus answered and said, “You will become the thirteenth, and you will be cursed by the other generations — and you will come to rule over them. In the last days they will curse your ascent [47] to the holy [generation]”] [“But you will exceed all of them. For you will sacrifice the man that clothes me.”] [“Already your horn has been raised, your wrath has been kindled, your star has shown brightly, and your heart has … [57]”]
"And in the previous passage: First: Judah is made to resemble Jesus and is crucified instead of him, and he sacrifices himself. Second: Judah will come at the end times to prevail. So Judah who is mentioned in some passages of the Gospel such as the previous one must be other than Judas Iscariot* who turned Jesus in as in the end of the Gospel of Judah, [They approached Judas and said to him, “What are you doing here? You are Jesus’ disciple.” Judas answered them as they wished. And he received some money and handed him over to them.] Gospel of Judah, Scene 3. Turning to the fact that the word Judah means praise or Ahmed in Arabic, meaning the name of the Mahdi or the Savior or the Comforter promised at the end times; it is thus clarified that the intended one by the other Judah who was made to resemble Jesus, and was crucified instead of him, and who Jesus℗ spoke to, saying that he will return and rule at the end times, is the Savior and the Comforter and the Mahdi, Ahmed, mentioned in the Torah, the Gospel, the Quran and the Will of the Messenger of God Muhammad, peace be upon him and his progeny." - from Book- 13th Disciple by Ahmed al-Hasan a.s. page 46.
Lookalike of Jesus pbuh from the descendants of Imam Ali ibn Abi Talib a.s.
And it was narrated that the crucified look-alike is from the lineage of the Messenger of God℗: The Messenger of God Muhammad℗ said in his supplication for Ali bin Abi Talib℗, ﴾“O God! Grant him the patience of Moses, and make among his descendants the look-alike of Jesus℗. O God! Indeed, You are my vicegerent upon him and upon his progeny and his kind and purified lineage from whom You have removed uncleanliness and impurity.”﴿*
Al-Ghayba (The occultation) by al-Numani page 144.
Will of the Prophet Muhammad pbuhap on the night of his death:
The Prophet Muhammad pbuhap said to Ali bin Abi Talib on the night of his death,
“O Father of Al-Hassan, bring me a pen and a paper”, and he dictated his will until he came to a position where he said, “O Ali, there will be twelve Imams after me and after them there will be twelve Mahdis. You, O Ali, are the first of the twelve Imams, Allah has named you in his heavens Ali Al- Mortatha, The Prince of the Believers, the Grand Truthful, the Bright Differentiator between truth and falsehood, the trusted, and the Mahdi (the rightly guided). These names may not to be truly attributed to other than you. O Ali, you are my successor over my family, their living and their deceased, and over my women. Whomever you affirm shall find me tomorrow, and whomever you reject I am innocent of her. I will not see her and she will not see me on the Day of Resurrection. And you are the successor (Khalifa) upon my nation after me. If death approaches you, hand it over to my son Al-Hassan the very beneficial. Then if death approaches him, let him hand it over to my son Al- Hussein, the martyr, the pure, the assassinated. Then if death approaches him, let him hand it over to his son, the master of the worshippers, Ali. Then if death approaches him, let him hand it over to his son, Muhammed Al-Baqir. Then if death approaches him, let him hand it over to his son, Jafar Al-Sadiq. Then if death approaches him, let him hand it over to his son, Musa Al-Kathum. Then if death approaches him, let him hand it over to his son, Ali Al-Retha. Then if death approaches him, let him hand it over to his son Muhammad, the trustworthy, the pious. Then if death approaches him, let him hand it over to his son Ali, the advisor. Then if death approaches him, let him hand it over to his son Al-Hassan, the virtuous. Then if death approaches him, let him hand it over to his son, Muhammad the Entrusted of the Holy Family of Muhammad peace be upon them. So these are the twelve Imams. Then after him, there will be twelve Mahdis. So if death approaches him, let him hand it over to his son, the first of the close ones, he has three names, one like mine and my father’s: Abdullah (servant of Allah), Ahmad and the third name is The Mahdi (rightly guided). He is the first of the believers.”
