Some people said, "O Allah's Messenger (ﷺ)! Meat is brought to us by some people and we are not sure
whether the name of Allah has been mentioned on it or not (at the time of slaughtering the animals)."
Allah's Messenger (ﷺ) said (to them), "Mention the name of Allah and eat it."
Sahih al-Bukhari Book 34, Hadith 11
