«الصيام جنة وإذا كان أحدكم صائما فلا يرفث ولا يجهل وإن امرؤ قاتله أو شاتمه فليقل: إني صائم مرتين والذي نفسي بيده لخلوف فم الصائم أطيب عند الله من ريح المسك يترك طعامه وشرابه وشهوته من أجلي الصيام لي وأنا أجزي به والحسنة بعشر أمثالها»
The Prophet (peace and blessings be upon him) said:
"Fasting is a shield. When one of you is fasting, he should neither speak obscenely nor act ignorantly, and if a man fights him or abuses him, he should say twice: 'I am fasting.' By the One in whose Hand is my soul! The smell of the fasting person's mouth is better with Allah than the fragrance of musk. He gives up his food, his drink and his desire for My sake; fasting is for Me and I Myself will reward it, and a good deed is recorded as ten times its like."
