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)."  

لاَ يُضَحَّى بِالْعَرْجَاءِ بَيِّنٌ ظَلَعُهَا وَلاَ بِالْعَوْرَاءِ بَيِّنٌ عَوَرُهَا وَلاَ بِالْمَرِيضَةِ بَيِّنٌ مَرَضُهَا وَلاَ بِالْعَجْفَاءِ الَّتِي لاَ تُنْقِي  

Another chain from the Prophet ﷺ with similar meaning.  

عَنِ النَّبِيِّ ﷺ نَحْوَهُ بِمَعْنَاهُ
