hi kai.
please find my answers to all your questions
1. Allah saved his messenger and prophet from unneeded hardship. Why is it a lie ? Was God lying in the Bible when he allowed the Pharoah and his army to think that they too could cross after Moses and his people but then drowned them all ?
Also, there was no reason in Islam for Jesus to suffer like that. Only Christians think that his dying saves them and wipes their sins, in Islam, if Jesus had died he would have wiped away nobody sins, so why would Allah let him die like that?
Who said it was in Secret ? His followers knew. Just because in the Bible it isn't stated doesn't make ti a fact.
Also who said it was another copy of Jesus ? The verse says 'Shubihah lahum' they THOUGHT it was him. Nothing says a copy of Jesus was substituted.
Don't forget that the Romans didn't know what Jesus looked like and had to take Judas to show them which one was Jesus. Most of the Jews didn't know either, only his followers knew.
In Addition, the Bible itself is confused on the issueof Jesus, one Gospel says Jesus carried the Cross the other Gospel says Simone carried it. They themselves didn't know which one was Jesus.
The cruciifed someone the THOUGHT was Jesus (maybe Simon). Thats all the Qur'an says.
2.Not clarified of all falsehood but PURIFIED of all Blasphemy. Allah took him up and purified him of those who blasphemed.
Verse 3.52 says that Jesus detected Kufr amongst them. This is what he was purifed from and is STILL being purified. The verse speaks of purification in the continious tense not in the past tense.
There were two types of people back then for Jesus to be purifed from, (1) those who thought he was God/Son of God and they existed at his time too, and there were the Jews who wouldn't beleive he was a messenger and tried to kill him.
3.Every messenger of allah had his own unique Gift, Moses was spoken to by allah from behind a bush, Jesus was a virgin birth and healing the sick and Mohamed's gift was that he was the final prophet and a mercy to the Worlds (not just a small group of people).
hope to have clarified.
