Sahih al-Bukhari Book 34, Hadith 11
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."
that his uncle said: "The Prophet (ﷺ) was asked: If a person feels something during his prayer; should one interrupt his prayer?" The Prophet (ﷺ) said: No! You should not give it up unless you hear a sound or smell something." Narrated Ibn Abi Hafsa: Az-Zuhri said, "There is no need of repeating ablution unless you detect a smell or hear a sound."
While we were offering the prayer with the Prophet (ﷺ) a caravan carrying food came from Sham. The people looked towards the caravan (and went to it) and only twelve persons remained with the Prophet. So, the Divine Inspiration came; "But when they see some bargain or some amusement, they disperse headlong to it." (62.11)
