I was reading the koran and also articles from Christian apologist and the issue that comes up in my mind is that I have read anything outside of the koran and the gospel of infancy that speaks about Jesus speaking from the cradle.

in these gospels Thomas in particular it says that Jesus killed a young guy because he bumped into him, does that sound like the sinless Jesus Christ?

this gospel is not trusted by Christians which is quite obvious but verses of it have found its way into the koran.

are there any Muslims that can explain why this is.
