How can sculpting/drawing be Haram when Isa (PBUH) sculpted a bird?

I would like to see a scholarly commentary or quote explaining why Isa (PBUH) is allowed to form things from clay (3:49) but Muslims are not allowed. Sculpting/forming out of clay is usually frowned down upon far more than drawing, so this should be interesting. > And [make him] a messenger to the Children of Israel, [who will say], 'Indeed I have come to you with a sign from your Lord in that I design for you from clay [that which is] like the form of a bird, then I breathe into it and it becomes a bird by permission of Allah . And I cure the blind and the leper, and I give life to the dead - by permission of Allah . And I inform you of what you eat and what you store in your houses. Indeed in that is a sign for you, if you are believers.
