Sayyiduna Bara’ bin Azib (may Allah be pleased with him) said that the Messenger of Allah (peace and blessings be upon him) was asked:“What kind of animal should be avoided for sacrifice?”He replied:“Firstly, a one-eyed animal whose defect is obvious; (secondly) a lame animal whose lameness is evident; (thirdly) a sick animal whose sickness is clear and apparent; and (fourthly) an extremely thin sacrificial animal whose bones contain no marrow.”
