"Our companions narrated to us that Abu 'Ubaidah said: 'Fasting is a shield, so long as you do not damage it."'
Sunan an-Nasa'i Book 22, Hadith 146
← Previous Hadith "Fasting is a shield against the Fire. Whoever starts the day of fasting, let him not act in an ignorant manner during that day. If anyone treats him in an ignorant maner, let him not insult him or curse him, rather let him say: "I am fasting.' By the One in whole hand is the soul of Muhammad, the smell that comes from the mouth of a fasting person is better before Allah than the fragrance of musk."
