"O you who
believe! Fasting is prescribed for you as it was prescribed for
those before you, that you may become Al-Muttaqun (the pious)."
Abu Huraira related
that the Prophet (peace and blessings be upon him) said: Whoever
fasts during Ramadan with faith and seeking his reward from Allah
will have his past sins forgiven. Whoever prays during the nights
in Ramadan with faith and seeking his reward from Allah will have
his past sins forgiven. And he who passes Lailat al-Qadr in prayer
with faith and seeking his reward from Allah will have his past
sins forgiven (Bukhari, Muslim).
Abu Huraira related
that Rasulullah said: If anyone omits his fast even for one day
in Ramadan without a concession or without being ill, then if
he were to fast for the rest of his life he could not make up
for it (Bukhari).
Abu Huraira related
that the Prophet said: Allah the Majestic and Exalted said: "Every
deed of man will receive ten to 700 times reward, except Siyam
(fasting), for it is for Me and I shall reward it (as I like).
There are two occasions of joy for one who fasts: one when he
breaks the fast and the other when he will meet his Lord"
(Muslim).
Abu Huraira related
that Rasulullah said: Many people who fast get nothing from their
fast except hunger and thirst, and many people who pray at night
get nothing from it except wakefulness (Darimi).
