´Narrated Al-Bara' bin 'Azib:` A Marfu' narration (from the Prophet (ﷺ)), saying: "A crippled animal whose limp is obvious is not to be slaughtered as sacrifice, nor an animal with a bad eye whose blindness is obvious, nor a sick animal whose sickness is obvious, nor an emaciated animal that has no marrow (in its bones)."
