question #1 Sahih al-Bukhari 5499, Book 72, Hadith 25 : What is the significance of mentioning Allah’s name during the act of slaughtering animals in Islam?

Allah’s Messenger (ﷺ) said that he met Zaid bin `Amr Nufail at a place near Baldah and this had happened
before Allah’s Messenger (ﷺ) received the Divine Inspiration. Allah’s Messenger (ﷺ) presented a dish of meat (that
had been offered to him by the pagans) to Zaid bin `Amr, but Zaid refused to eat of it and then said (to
the pagans), “I do not eat of what you slaughter on your stonealtars (Ansabs) nor do I eat except that
on which Allah’s Name has been mentioned on slaughtering.”
