Narrated Abu Huraira: Allah's Apostle said, "Fasting is a
shield (or a screen or a shelter). So, the person observing
fasting should avoid sexual relation with his wife and should
not behave foolishly and impudently, and if somebody fights
with him or abuses him, he should tell him twice, 'I am
fasting." The Prophet added, "By Him in Whose Hands my soul
is, the smell coming out from the mouth of a fasting person is
better in the sight of Allah than the smell of musk. (Allah
says about the fasting person), 'He has left his food, drink
and desires for My sake. The fast is for Me. So I will reward
(the fasting person) for it and the reward of good deeds is
multiplied ten times."
The Prophet said, "There is a gate in Paradise called
Ar!Raiyan, and those who observe fasts will enter through it
on the Day of Resurrection and none except them will enter
through it. It will be said, 'Where are those who used to
observe fasts?' They will get up, and none except them will
enter through it. After their entry the gate will be closed
and nobody will enter through it."
Narrated 'Alqama: While I was walking with `Abdullah he said,
"We were in the company of the Prophet and he said, 'He who
can afford to marry should marry, because it will help him
refrain from looking at other women, and save his private
parts from committing illegal sexual relation; and he who
cannot afford to marry is advised to fast, as fasting will
diminish his sexual power."
The Prophet used to kiss and embrace (his wives) while he was
fasting, and he had more power to control his desires than any
of you. Said Jabir, "The person who gets discharge after
casting a look (on his wife) should complete his fast."
(the wife of the Prophet) Hamza bin `Amr Al?Aslami asked the
Prophet, "Should I fast while traveling" The Prophet replied,
"You may fast if you wish, and you may not fast if you wish."
