Fasting the month of Ramadan is
one of the five pillars of Islam, as
the Prophet (may the blessings and
peace of Allah be upon him) said,
"Islam is based on five
(principles): to testify that none
has the right to be worshipped but
Allah and Muhammad is Allah's
Messenger, to establish the
(obligatory) prayers dutifully and
perfectly, to pay Zakah (i.e.
obligatory charity), to perform
Hajj. (i.e. Pilgrimage to Makkah),
to observe fast during the month
of Ramadan." Agreed upon: 8, 16].
