Jesus spoke while Still in the Cradle is in itself is the biggest miracle. As Qur'an mentions :

   She pointed towards him. They said, "How can a baby in the cradle speak?" He said, "I am the slave of Allah. He has given me the Book and made me a Prophet. He has made me blessed wherever I am and directed me to do prayer and pay poor-due as long as I live, and to show devotion to my mother. He has not made me insolent or arrogant. Peace be upon me the day I was born, and the day I die and the day I am raised up again alive."
(Surah Maryam: Verses 29-33)

Now the child was the product of a miracle and consequently, miraculous things began to happen. In defense of his mother and of the truth, the infant Jesus spoke saying, “I am a servant of God. He has given me Scripture and has made me a Prophet. He has blessed me wherever I may be and has made prayer and charity my duty as long as I live.” This put the detractors to rest. Throughout his youth, Jesus remained dutiful to his mother and developed quickly in intelligence, wisdom, and piety. He dumfounded the learned and was greatly admired by those around him who appreciated his talents. He claimed to be a sign of God and a Messenger to the Israelites. His people had strayed from the spirit of truth and placed their trust in legalism, thereby burying their sense of mercy beneath dusty scrolls and rituals.

Finally, when he came of age, Jesus began to travel and preach throughout the land of Palestine about a return to the truth of the old revelations and a rejection of all that man had added. In his task he was supported by the spirit of truth, the angel Gabriel.

He also healed the sick, uplifted the distressed and revived the dead. All these things he did with the permission of God, never taking credit for them himself.
