Is the meat of an animal slaughtered by someone who says "Bismillah Bismil-Rasul (In the name of Allah, in the name of the Messenger)" permissible to eat?

If the slaughterer says, "In the name of Allah, in the name of the Messenger," and it becomes clear that he said it spontaneously, then there is no harm in eating the slaughtered animal. However, if he intended to seek help from the Prophet, peace be upon him, or associate him with Allah in the slaughter, then this is a grave religious prohibition; because seeking help in this context should only be sought from Allah, and slaughtering for other than Allah is forbidden by sacred law, due to His saying, the Almighty: "So pray to your Lord and sacrifice," and His saying: "Say, 'Indeed, my prayer, my rites of sacrifice, my living, and my dying are for Allah, Lord of the worlds,'" and the hadith: "Allah curses whoever slaughters for other than Allah."
