Acts which do not break the fast
By Mufti Muhammad

To eat or drink forgetfully
If a person forgets that he is fasting and eats, drinks or has sexual intercourse, then the fast will not break whether the fast is fardh (compulsory) and wajib or nafl (optional). If a person was reminded that he was fasting but even then he did not remember and kept on eating and drinking then his fast will break. In this case only Qadha is due not Kaffarah.
The ruling about reminding a fasting person is that if the fasting person is quite strong then it is wajib to remind him that he is fasting, but if he is a weak person and is greatly affected by fasting, then it is better not to remind him at all.
(Fathul Qadeer Pg254 Vol.2, Raddul Muhtar Pg49, Vol.2)

Fragrance and smoke
By inhaling a fragrance of any type and however strong, the fast will not break. Similarly if dust, a fly or some smoke goes down the throat unintentionally then the fast will not break. However, if one did this intentionally then the fast will break. For example incense sticks are being burnt and a person goes and sits near them and inhales the smoke, the fast will break.
(Raddul Muhtar P395, Vol. 2 and the other books)

Antimony and oil etc.
It is permissible to apply surmah (antimony) in one's eyes or put eye drops when one is fasting. Oil can also be put on the beard. Even if after applying surmah the colour of the surmah appears in one's saliva or the taste is felt in the throat, the fast will not be broken. The only condition is that those things are used in need and the object is not to look beautiful and show off. If the purpose to use these things is show then it will be makruh to use them.

Miswaak
Just as to cleansing the teeth with miswaak is sunnat while performing the wudhu for a non-fasting person, it is also sunnat for a fasting person, whether it is used during the day or night, or whether it is wet or dry. If the thread of the miswaak went down the throat unintentionally then the fast will not break either.
(Ahsan-ul-Fatawa P445, Vol.4)

Rinse the mouth etc.
If a fasting person, already in a state of wudhu, rinses his mouth, takes a bath, or ties a wet cloth around his body with only the intention of keeping cool then his fast will not break. If he does so just to show his impatience and intolerance then it will be makruh for him to do so.
(Maraq-il-Falah with Al-Tahtavie Pg372 and other common books)

Fast is not breached in all these cases:
A herbal medicine was grounded and its taste was felt in the throat; or a cotton bud or something else was used to clean the ear and it became stained with wax and it was put inside the ear again; or something smaller in size than a chickpea was lodged in the teeth and was swallowed; or blood came out of the teeth, reached the throat but did not go into the stomach, or if it did reach the stomach but was lesser in quantity than the salvia; or if one cleared his nose and the phlegm or thick mucus went into the throat and then into the stomach; or if one cleared his throat and swallowed the phlegm, whether it was inside the nose or throat or it had come out and was swallowed before the flow had broken; or if while speaking saliva came out outs the lips and the fasting person licked it; or if something as tiny as a sesame seed was put in the mouth and chewed and it went down the throat but its taste was not felt, then in all these cases the fast is not broken.
(Maraq-il-Falah with Al-Tahtavie Pg362, Radd-ul-Muhtar Pg397, Vol.2)

If a betel-leaf was chewed before subh-e-sadiq and the mouth was cleansed thoroughly but later in the day, the reddish colour can still be seen in the saliva then the fast will not be breached by swallowing that saliva.
(Ma`alim-ul-tanzeel, pg.139, Vol.4)

If a person vomited involuntarily then the fast is not lost whether it be small or large in quantity. But if one vomited intentionally and it was a mouthful then the fast is lost. If it was less then a mouthful, the fast is not breached.

If a bit of vomit came and returned to the throat of its own, then the fast is not broken. But it will be broken if returned intentionally by the fasting person
If someone burnt incense near him and smelled it purposely then the fast is broken. Similarly smoking a huqqa, cigarette or tobacco breaks a fast. It is permissible to smell perfume of a rose etc. in which there is no smoke.

If a person put some smelling powder in his nose or oil in his ear or used something in the back hole to facilitate motion, though he did not drink any medicine, then the fast is broken. But only compensatory fast and no recompense (fidyah) is due. The fast is not broken by pouring water in the ear.


Misconceptions about fast
By Mufti Muhammad

Like other Ibadaat, or forms of worship there are many misconceptions concerning fasts that need to be corrected. Some of the misconceptions are pointed out here.

Giving up fast without reason
For an incapable person, it is permissible not to keep fast or to break fast in some conditions, but everyone cannot decide who is incapable in the sight of Shariah. Some indolent people do not keep fasts on the assumption that they are not able to keep them. In fact, if they try to keep fasts, they can do it easily. But they call their indolence and laziness 'incapability'. Some people have self-made incapability. For example, it is allowed in Shariah to give up fasting during a journey. Some people leave home without any aim or reason and go on a journey. It is not permissible to decide one's incapability without consulting a mufti.

Paying Fidya without being permanently incapable
Some careless people miss fasts thinking that they will pay Fidya, whereas Fidya can only be paid by a person who is incapable of fasting and there is no hope of his recovery. If such a person becomes capable of fasting at any time before death, the Fidya he has given will no longer be valid.

Forbidding an adolescent to keep fast
Even some religious people do not make their children keep fasts though the children's age, health and body strength is such that they can easily do so. Fasting is not compulsory upon children before they attain adulthood, but it is incumbent upon the guardians to make the children keep fasts if they are near adulthood and can sustain it. If the child is fond of worship at an early age, he will face no difficulty in discharging religious duties after becoming an adult.

Incapable person not benefitting from remission
Some people are on the other hand go to the other extreme and do not benefit from the remission given by Shariah. Some people for example do not give up fasting even during a hard journey or illness. Some pregnant women or those having a suckling baby do keep fasts at the cost of their own health and that of their child. Some misguided people make their minor children keep fasts even though they cannot sustain it. All these things are the result of staying away from Ulama's company and not understanding the philosophy of Shariah.

Haste or delay in 'sehri'
Some people take 'sehri' at midnight. Though such haste is allowed, but it is against the actual philosophy of 'sehri'. The meal is meant to prevent weakness and retain strength during the fast. Some people mistakenly think that after taking sehri, one cannot eat or drink anything though it is still night and there is still time left. It is necessary to abandon this misconception.

On the other hand, some people make so much delay in taking sehri that it puts their fast in doubt. They keep looking at their watches and charts to see how many minutes are left, whereas there is a chance of mistake in both of them. Thus, prudence demands that one should stop taking sehri a few minutes before the time on watch and chart. Sometime people call azaan for Fajr prayer a few minutes before the due time thinking that people will stop taking sahri in this way. There are many wrongs in doing so. Therefore, azaan must be called at its due time.

Haste or delay in 'iftar'
Some people show too much haste in iftar thus putting their fast in doubt. There are discrepancies in charts. Times of sehri and iftar given on charts are not definite though they are very close mathematically. Some unwise people start iftar on hearing azaan on radio (though the azaan maybe of some other city). Usually, the sirens and azaan on radio are according to charts and cannot therefore be trusted fully. There have been occasions when the sun was still visible at the time azaan was called. On 13th Ramadan, 1397 A.H, Radio Pakistan broadcast azaan four or five minutes before the due time and replayed azaan from the beginning before the first one could end. Millions of people marred their fast by starting iftar at the first azaan. Therefore, it is vital to keep watches set at the standard time and start iftar three minutes after the time given on a chart. For a person who has shown patience for several hours, is it difficult to wait for two or three more minutes ? Some habitually doubtful people do not start iftar even after the time of sunset. Such a delay is prohibited in Hadith. Some people make so much delay in iftar that they miss the congregational prayer of Maghrib or miss one or two rakaat of it. Sometimes, such people offer congregational prayer at home. Though it is b etter than praying alone, it is not in any way the substitute of congregational prayer a mosque.
