What is the wisdom behind forbidding eating from the slaughter of one who abandons prayer, while it is permissible to eat from the slaughter of a disbeliever from the People of the Book?

Question:
May Allah reward you. Honorable Shaykh, a questioner says: Regarding the saying of Allah the Exalted, what is the wisdom behind the prohibition of the meat slaughtered by one who abandons prayer, given that he believes in Allah, in Muhammad (peace and blessings be upon him), and in all the prophets, whereas the People of the Book do not believe in Muhammad (peace and blessings be upon him)?

Answer:
This is an apostate, my brother. The one who abandons prayer is an apostate, and an apostate has no religion. As for the People of the Book, they have a religion; their foundation is sound. They believe in Allah, they believe in the angels, and they believe in the general message of the Messenger. As for the apostate, he does not believe in anything; he has exited the religion. Therefore, his slaughter is not permissible. And your statement that he believes in Allah while he is an apostate is a mistake. He does not believe in Allah; the faith has gone, may Allah protect us, unless he repents to Allah the Exalted. Yes.
