The Quran has a few stories of Christ's childhood that are contradicted by Luke in Acts 1:1. These childhood stories of Christ miracles are fabrications. They want the Quran to seem superior to the gospels in content, so adding a few stories could sway the gullible. Yet, the gospels do have defenses. Consider Jesus turning water to wine, it is called Christ's beginning of miracles.
John 2:11
This beginning of miracles did Jesus in Cana of Galilee, and manifested forth his glory; and his disciples believed on him.
If Jesus had done miracles openly before this he would have had a following already. This miracle is when his disciples started to believe on him. Previous to the miracle they were expecting a messiah intellectually from the prophets, but the miracle strengthened this into a stronger faith.
Luke also contradicts the Quran. Luke doesn't mention childhood miracles performed by Christ, though he wrote of all things from the beginning.
Acts 1:1
The former treatise have I made, O Theophilus, of all that Jesus began both to do and teach,
The word began in Greek means orderly from the beginning. It includes "all" Jesus did and taught from a kingdom perspective. It doesn't reflect on all of Christ's daily life. We can say with certainty that childhood miracles were not included in the Apostles' ministry.
Luke 1:2
Even as they delivered them unto us, which from the beginning were eyewitnesses, and ministers of the word;
The official record did not contain childhood miracles, because they didn't exist. It is obvious Jesus was an immensely wonderful child, but this did not include miracles.
Luke 1:3
It seemed good to me also, having had perfect understanding of all things from the very first, to write unto thee in order, most excellent Theophilus,
Luke 1:4
That thou mightest know the certainty of those things, wherein thou hast been instructed.
We see that childhood miracles were not part of Apostolic instruction. We can see the Quran is a false gospel.
