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)." (Using translation from Tirmidhī 1497)
سُئِلَ رَسُولُ اللَّهِ ﷺ مَا يُتَّقَى مِنَ الضَّحَايَا؟ قَالَ «الْعَوْرَاءُ الْبَيِّنُ عَوَرُهَا وَالْعَرْجَاءُ الْبَيِّنُ ظَلْعُهَا وَالْمَرِيضَةُ الْبَيِّنُ مَرَضُهَا وَالْعَجْفَاءُ الَّتِي لَا تُنْقِي»
