Is it permissible to supplicate for the nose to return to its original shape, as it was before the cosmetic surgery that disfigured it? And is it possible for Allah to answer this supplication and for the nose to revert to its former shape, given that doctors have confirmed the impossibility of another surgery?

What you have done by undergoing an operation on your nose to increase beauty is forbidden, for it involves changing the creation of Allah and obeying Satan. Allah has cursed the tattooist and the tattooed, the one who plucks eyebrows and the one who has them plucked, and those who file their teeth for beauty, altering Allah's creation. Perhaps what has afflicted you is a punishment. There is no blame upon you for asking Allah to rectify your condition, improve your appearance, and restore it to what it was or even better. You must be patient with Allah's decree and destiny.
