on the authority of abu ya'laa shaddaad bin aws (radiallaahu anhu), that the messenger of allaah sallallaahu alayhi wa sallam said :
| verily allaah has prescribed ihsaan (proficiency, perfection) in all things. so if you kill then kill well; and if you slaughter, then slaughter well. let each one of you sharpen his blade and let him spare suffering to the animal he slaughters. |

and his (sallallaahu alayhi wa sallam) statement "then kill well" is general to all situations, whether it be slaughtering animals, or killing a human in qisaas (equal retaliation) or killing as a shari'ah punishment, or other than that.
this hadeeth is from the comprehensive statements of the prophet sallallaahu alayhi wa sallam, and contains many principles. and the meaning of "killing well" is that one exerts himself the utmost in performing it well, and does not intend to cause unnecessary pain or torment through it. and "slaughtering well" in respect to livestock implies that one shows kindness to the animal to be slaughtered, and that one does not fell it to the ground cruelly or harshly, nor drag it from one place to another. it also includes facing it towards the qiblah and taking the name of allaah upon it, and cleanly and quickly cutting the throat and the two jugular veins, and then leaving it until it has turned cold. and it also includes recognising and acknowledging allaah's favours upon us, and thanking him and being grateful to him for them, for verily he - subhaanahu - has subdued for us from amongst his creation whatever pleases him, and has made permissible for us what he could have made forbidden, if he had so wished.
