How should a surgeon pray when the times for prayer are close together in the winter?.Dought & clear - ,

about prayer whilst doing surgery or afterwards. I work as a doctor
and the day is very short in Canada during the winter; Maghrib comes
at 5 p.m. Hence the time between the prayers is very short and I do
not know how the surgeon can do his work when this time is very short.
Hence I think it is better to make the prayers up afterwards. What is
your opinion on that?
Praise be to Allaah.
It is obligatory to offer the prayers on time as enjoined by Allah,
may He be exalted, and it is not permissible to delay them except in
the case of an excuse that make itpermissible to put prayers together.
Allah, may He be exalted, says (interpretation of the meaning):
"Verily, the prayer is enjoined on the believers at fixed hours"
[an-Nisa' 4:103].
Being careless about the prayer and delaying it until the time for it
is over without any excuse is a major sin, because Allah, may He be
exalted,says (interpretation of the meaning):
"Then, there has succeeded them a posterity who have given up As-Salat
(the prayers) (i.e. made their Salat (prayers) to be lost,either by
not offering them or by not offering them perfectly or by not offering
them in their proper fixed times, etc.) and have followed desires. So
they will be thrown in Hell"
[Maryam 19:59].
Ibn Mas'ood (may Allah be pleased with him) said concerning the word
ghayy (translated here as "Hell"): This is a valley in Hell which is
very deep and foul.
The Prophet (blessings and peace of Allah be upon him) said: "Whoever
fails to pray 'Asr, his good deeds will be rendered invalid." Narrated
by al-Bukhaari,553.
With regard to putting together Zuhr and 'Asr, and Maghrib and 'Isha',
at the time of the earlier or later prayer, that is permissible in the
case of excuses that have been defined by the scholars, one of which
is so as to alleviate hardship and difficulty. This is appropriate in
thecase mentioned here. If the doctor is afraid that if the surgery
takes a long time and when he has finished, the time for'Isha' prayer,
for example, will have ended, then he may put Maghrib and 'Isha'
together at the time of the earlier prayer, and offer them at the time
ofMaghrib. If he is going to start surgery before the time for Maghrib
begins, and he will finishbefore the end of the time for 'Isha', then
he may delay Maghrib and put it together with 'Isha' at the time of
the later prayer, after he hasfinished doing surgery. The same applies
with regard to Zuhr and 'Asr.
The evidence for that is the report narrated by Muslim (705) from Ibn
'Abbaas (may Allah be pleased with him) who said: The Messenger of
Allah (blessings and peace of Allah be upon him) put together Zuhr and
'Asr, and Maghrib and 'Isha', in Madeenah when there was no fear and
no rain. According to the hadeeth of Wakee' he said: I said to Ibn
'Abbaas: Why did he do that? He said: So that his ummah would not
besubjected to hardship.
Whenever there is difficulty and hardship, it is permissible to put
together Zuhr and 'Asr, and Maghrib and 'Isha'. With regard to Fajr,
it cannot be put together with anything else before or after.
Prayer is extremely important, and it is a serious matter. It is the
first thing for which the individual will be brought to account, so
itis essential to pay attention to it and offer prayer regularly and
on time.
We ask Allah to help and guide you.
