"IU said to Al-Bara bin Azib: 'Tell me of the sacrificial animals that the Messenger of Allah disliked or forbade, He said: The Messenger of Allah stood up, and my hands are shorter than his, and he said: "There are four that will not do as sacrifices: the animals that clearly has one bad eye: the sick animals that is obviously sick; the lame animal with an obvious limp; and the animal that is so emaciated that it is as if three is no marrow in its bones."' I said: "I dislike that the animals should have some fault in its horns or teeth' He said;'what you dislike, forget about it and do not make it for bidden to anyone."" (Using translation from Nasāʾī 4369)  

حَدَّثَنِي عَمَّا نَهَى عَنْهُ رَسُولُ اللهِ ﷺ مِنَ الْأَضَاحِيِّ قَالَ قَامَ رَسُولُ اللهِ ﷺ وَيَدِي أَقْصَرُ مِنْ يَدِهِ قَالَ «أَرْبَعٌ لَا يَجُزْنَ الْعَوْرَاءُ الْبَيِّنُ عَوَرُهَا وَالْمَرِيضَةُ الْبَيِّنُ مَرَضُهَا وَالْعَرْجَاءُ الْبَيِّنُ ظَلْعُهَا وَالْكَسِيرَةُ الَّتِي لَا تُنْقِي» قُلْتُ إِنِّي أَكْرَهُ أَنْ يَكُونَ فِي الْقَرْنِ نَقْصٌ وَأَنْ يَكُونَ فِي السِّنِّ نَقْصٌ قَالَ «مَا كَرِهْتَهُ فَدَعْهُ وَلَا تُحَرِّمْهُ عَلَى أَحَدٍ»
