Narrated `Abbas bin Tamim: that his uncle said: "The Prophet was asked: If a person feels something during his prayer; should one interrupt his prayer?" The Prophet 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."

Narrated `Aisha: Some people said, "O Allah's Apostle! 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 Apostle said (to them), "Mention the name of Allah and eat it."
