Isa is Jesus, Mother was Mary who was a descendent of Imran (Amram in the Torah) = Family of Imran. The mother of Mary is not NAMED, she is 'a woman of Imran' nor is it clear as mud who the mother of Mary was in the Torah or the rest of the books. What is clear is that Moses and Jesus did not exist at the same time and that Miriam was a VERY common name. Jesus and John the baptist existed at the same time and Mary, mother of Jesus, visited Elizabeth the mother of John and wife of Zacharia while they were both pregnant at the same time. Miriam, sister of Aaron and Moses was a long time before this.
That's my take on it
When you say Isa is Jesus, did you consider the fact stated in both Quran and Gospel about how they died?
Quran said:4:157 And their saying: "We have killed the Al Masih, son of Maryam, messenger of God!" And they had not killed him, nor crucified him, but it appeared to them as if they had. And those who dispute are in doubt regarding him, they have no knowledge except to follow conjecture; they did not kill him for a certainty.
(38) At the same time two robbers were crucified with Him, one on the right hand and one on the left.
(50) And Jesus cried again with a loud voice and gave up His spirit.
I saw you compiled the information about family tree from both Quran and Gospel to get the conclusion that Isa is Jesus, but you did not take into account that both Kitab has different information about their death.
Did God sent down different information about their death? Why God didn't tell people in Gospel that it wasn't Jesus that they had crucified?
Why God sent down different information about him, if Isa is Jesus?
Did you could find any miraculously story about Jesus had been replaced by someone at the cross, from Al Quran or Gospel?
I think Al Quran is consistent about it, and so does Gospel. It is our mind having that inconsistency. They were not the same person.
It is our mind dare enough to say that there are two Maryam in Al Quran, just to support that Isa is Jesus, but didn't provide anything when both Kitab said something different about their death.
The fact is they did not crucify Isa:
4:157 And their saying: "We have killed Al Masih, Isa, son of Maryam, messenger of God!" And they had not killed him, nor crucified him, but it appeared to them (like Isa) <shubbiha lahum> . And those who dispute are in doubt regarding him, they have no knowledge except to follow conjecture; they did not kill him for a certainty.
and also the fact that some people had tried to imitate God's creation, explained using the same triliteral root shīn bā hā which also used in 4:157:13:16 Say: "Who is the Lord of the heavens and the earth?" Say: "God." Say: "Have you taken besides Him allies who do not possess for themselves any benefit or harm?" Say: "Is the blind and the seer the same? Or do the darkness and the light equate? Or have they set up partners with God who have created like His creation, so the creation seemed alike <fatashābaha> to them?" Say: "God has created all things, and He is the One, the Supreme."
I disagree, the Quran is a part of The Book which consists of Torah, Gospel and Quran. It is the completion of the message and in it are many references to to the other 'portions of the Book' given before it.
And Allah has warned us about the man made Kitab:2:79 So woe to those who write the Book with their hands then say: "This is from God," so that they can purchase with it a cheap price! Woe to them for what their hands have written and woe to them for what they gained.
And the people whose confound the truth with falsehood :3:71 "O people of the Book, why do you confound the truth with falsehood and conceal the truth while you know?"
With this reality, I do not dare put the gospel as a reference to explain the contents of the Quran. If the Quran only mentions one Maryam, then indeed there is only one Maryam as the Mother of Isa and the daughter of Imran.
If you could consider Isa is Jesus according to how they had birth, you also have to consider the fact how they had died.
