Is it established from his way (peace and blessings be upon him) and the way of his Companions that when they intended to kill a captive from among the disbelievers, they would slaughter him?

Question:
May Allah reward you, Honorable Shaykh. This questioner says: Is it established from his way (peace and blessings be upon him) and the way of his Companions that when they captured a captive from among the disbelievers and intended to kill him, they would slaughter him as one slaughters a sheep?

Answer:
They offer him Islam; if he accepts Islam, otherwise they have the choice. If they wish, and if they see that the ransom is better, they redeem him. And if they see that killing him is better, they kill him. This is up to the one in authority. He slaughters him in whatever manner, with the sword, with the knife, in whatever manner. The important thing is that he does not torment him, as he (peace and blessings be upon him) said: So he does not torment; rather, he kills by the comfortable means that takes his soul. Yes.
