 The requirement that the animal is in no way damaged or injured precludes the practice of stunning, whether by poleaxe, slaughtering hammer, captive bolt pistol, gas, or electrocution.A 1935 fatwa by the Mufti of Dehli declared that stunning that does not kill the animal and thus is 'reversible' is allowed under Islamic law.Al-Azhar rector Muhammad el-Tayyeb el-Naggar confirmed in 1982 that stunning would not make the practice un-Islamic.
