وَعَنِ الْبَرَاءِ بْنِ عَازِبٍ
أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ سُئِلَ: مَاذَا يُتَّقَى مِنَ الضَّحَايَا؟ فَأَشَارَ بِيَدِهِ فَقَالَ: «أَرْبَعًا الْعَرْجَاءُ والبين ظلعها والعرواء الْبَيِّنُ عَوَرُهَا وَالْمَرِيضَةُ الْبَيِّنُ مَرَضُهَا وَالْعَجْفَاءُ الَّتِي لَا تَنْقَى»
a lame animal which obviously limps, a one-eyed animal which has obviously lost the sight of one eye, a sick animal which is obviously sick, and a lean animal which has no marrow. *i.e. his fingers. Malik, Ahmad, Tirmidhi, Abu Dawud, Nasai.
