Dought & clear - ,- Times of Prayers - He wants to put the prayers together on a permanent basis because he works atnight.

I have got a job that requires me to work thenight shift, and this
means that I have to sleep during the day. Is it permissible for me to
put Zuhr prayer togetherwith 'Asr, and Maghrib with 'Isha', on a
permanent basis, so longas I have the night shift at work? I want to
put them together so that I do not interrupt my sleep a great deal.
Praise be to Allaah.
What is required is to regularly offer the prayers at the proper
times, in obedience to the command of Allah (interpretation of the
meaning):
"Guard strictly (five obligatory) AsSalawat (the prayers) especially
the middle Salat (i.e. the best prayer Asr). And stand before Allah
with obedience (and do not speak to others during the Salat
(prayers))."
[al-Baqarah 2:238]
"Verily, the prayer is enjoined on the believers at fixed hours"
[an-Nisa' 4:103]
and so as to avoid being included in the words of Allah
(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 lusts. So
they will be thrown in Hell"
[Maryam 19:59].
Ibn Mas'ood (may Allah be pleased with him) said concerning
al-ghayy(translated above as "Hell"): It is a valley in Hell, very
deep and with a foul taste.
And Allah says (interpretation of the meaning):
"So woe unto those performers of Salat (prayers) (hypocrites),
Who delay their Salat (prayer) from their stated fixed times,"
[al-Ma'oon 107:4-5].
So try hard to wake up for the prayer; it will notmatter if your sleep
is interrupted, because you will get used to that in the future. We do
not know why you are asking about putting Maghrib and 'Isha' together,
because we cannot imagine that youspend the whole day until 'Isha'
asleep. Can you spend your life only between work and sleep? What
about paying attention to the rights of your family andbrothers, and
doing acts of worship to Allah such as going to the mosque, reading
Qur'aan, seeking knowledge and so on?
We ask Allah to help you and give you strength.
And Allah knows best.
