Is it permissible for a Muslim to supplicate to Allah to restore his amputated hand or to bring back a deceased relative, knowing that Allah has decreed this matter and His wisdom necessitated that it not return in this world, or is this considered an objection to Allah's preordainment and decree?

Asking God for things that will not happen, such as bringing the dead back to life or restoring youth, is considered an act of aggression in supplication, which is forbidden by His Almighty saying: (Call upon your Lord humbly and secretly. Indeed, He does not like aggressors). This includes asking for impossibilities or things that go against the cosmic laws, which prevents the supplication from being answered.
