What baby in the Quran made a rather long speech beginning with "Lo! I am the slave of Allah"?

---

Jesus

They said: How can we talk to one who is in the cradle, a young boy?

He [Jesus] spake: Lo! I am the slave of Allah. He hath given me the Scripture and hath appointed me a Prophet,

And hath made me blessed wheresoever I may be, and hath enjoined upon me prayer and almsgiving so long as I remain alive,

And (hath made me) dutiful toward her who bore me, and hath not made me arrogant, unblest.

Peace on me the day I was born, and the day I die, and the day I shall be raised alive! Quran 19:29-33
