This is the wording of Muslim's narration.

This is the school of al-Shafi'i.
Section: Matters of doubt fall into three categories. The first is that whose origin is prohibition, such as a slaughtered animal in a land where there are Magians and idolaters who perform slaughter.

The basis for this is the hadith of 'Adi ibn Hatim, that the Messenger of Allah, peace and blessings of Allah be upon him, said: "If you send your dog and it becomes mixed with a dog for which the name of Allah was not mentioned upon it, do not eat, for you do not know which of them killed it."
