The meaning of "killing well" is to exert oneself the utmost in performing the action well, without causing unnecessary pain or torment through it. “Slaughtering well" implies that we show kindness to the animal being slaughtered, do not push it to the ground cruelly or harshly, nor drag it from one place to another. It also includes facing it towards the Qibla, pronouncing the name of Allah upon it, cleanly and quickly cutting the throat and the two jugular veins, and finally leaving it until it has turned cold. This hadith also includes recognizing and acknowledging Allah's favors upon us, and thanking Him and being grateful to Him. Allah (swt) has subjected some of His creation to us, and made their meat permissible when He could have made it forbidden, if He had wished.
