Sheikh Muhammad bin
Saalih al-‘Uthaimeen رحمه الله said:
It is stated in al-Mawsoo’ah al-Fiqhiyyah,
vol.28, pg.73:
One
of the ways in which Allaah has made things easy for His slaves is that He has
only enjoined fasting upon those who are able to do it, and He has excused
those who are unable to fast for a legitimate sharr’i reason.
The legitimate reasons for which one may be
excused from fasting are as follows:
1 – Sickness
Sickness
means everything that means that a person is not healthy. Ibn
Qudaamah رحمه
الله said:
The scholars are
agreed that it is permissible for the sick person not to fast in general.
The basis of that is the aayah in which Allaah
سُبحانه
وتعالى says:
“... but if any of
you is ill or on a journey, the same number (should be made up) from other days..”
[al-Baqarah 2:184]
It was narrated that Salamah ibn al-Akwa’ رضي اللّه عنـه
said:
“When this aayah
was revealed –
‘And as for
those who can fast with difficulty, (e.g. an old man), they have (a choice
either to fast or) to feed a Miskeen (poor person) (for every day)’
[al-Baqarah 2:184]
–
those who wanted not to fast could do that, and pay the fidyah (i.e., feed one
poor person for each day).
That
remained the case until the following aayah was revealed, i.e., the verse:
‘And as for
those who can fast with difficulty, (e.g. an old man), they have (a choice
either to fast or) to feed a Miskeen (poor person) (for every day)..’
[al-Baqarah 2:185]
– so it abrogated it.”
The
sick person who fears that fasting may make his sickness worse or that it will
slow down his recovery or damage a part of his body, has the option of not
fasting, and
indeed it is Sunnah for him not to fast and it is makrooh for him to complete
his fast, because that may lead to his death. So he has to be
cautious and protect himself. Moreover, if the sick person is very ill, that
makes it permissible for him not to fast. But if a healthy person fears
difficulty or tiredness, it is not permissible for him to break his fast, if
all that happens to him when he fasts is that he becomes tired.
