He has polio and he does not pray in congregation sometimes

Question

Praise be to Allah.

Praying in
congregation is obligatory for men who are able for it, whether they are in
their home town or travelling, according to the more correct of the two
scholarly opinions, because of a great deal of evidence, which has been
quoted in the answers to questions no.

If you are
able to go to the mosque, then praying in congregation is obligatory for
you. You said that you usually pray in the mosque, praise be to Allaah. This
by the grace of Allaah and His blessing to you. So strive to show gratitude
for it, for gratitude increases the blessing, as Allaah says (interpretation
of the meaning):

“If you
give thanks (by accepting Faith and worshipping none but Allaah), I will
give you more (of My Blessings)”

[Ibraaheem 14:7].

Secondly:

Sleeping is
a (valid) excuse for not praying in congregation, so long as it is not due
to carelessness, such as staying up at night for no need and not making use
of the means to help one wake up. Al-Tirmidhi (177), al-Nasaa’i (615), Abu
Dawood (437) and Ibn Maajah (698) narrated that Abu Qataadah (may Allaah be
pleased with him) said: They told the Prophet (peace and blessings of
Allaah be upon him) about their sleeping and missing the prayer, and he
said: “There is no negligence when one is sleeping, rather there is
negligence when one is awake. If any one of you forgets to pray, or sleeps
and misses a prayer, then let him pray when he remembers.” Classed as saheeh
by al-Albaani in Saheeh al-Tirmidhi. This hadeeth is also narrated in
al-Saheehayn with similar wording.

Al-Mubaarakfoori said in Sharh al-Tirmidhi: “There is no negligence
when one is sleeping” means that negligence cannot be ascribed to the one
who sleeps and delays a prayer as a result.

“rather
there is negligence when one is awake” means that negligence and
shortcomings are committed by the one who is awake and fails to pray or
delays the prayer with no excuse. End quote.

The Standing
Committee for Issuing Fatwas was asked: A man prayed Fajr after the sun had
risen, and that became his habit every day for two years, because he claimed
that sleep overtook him, as he stayed up at night in cafes and watching
entertainment until after midnight. Is his prayer valid?

They
replied: It is haraam to delay prayers until after the time for them is
over. The adult Muslim must offer prayers on time – Fajr prayer and others –
by asking someone to wake him up for them or by using an alarm clock to wake
him up. It is haraam for him to stay up late watching entertainment etc as
Allaah has forbidden him to stay up late doing things that will prevent him
from offering Fajr prayer on time or in congregation. The Prophet
(peace and blessings of Allaah be upon him) forbade staying up after ‘Isha’
for no legitimate shar’i reason. Every deed that will cause a delay in
praying until the time for the prayer is over is haraam, unless an exception
is made in sharee’ah. End quote from Fataawa al-Lajnah al-Daa’imah
(6/15).

Thirdly:

If you stay
away from offering Zuhr prayer in congregation for a valid reason, such as
not being able to go to the mosque, there is no sin on you. But if there is
no excuse then you have to repent to Allaah and offer the prayer in
congregation in the future.

We ask
Allaah to help you to do that which He loves and which pleases Him.

And Allaah
knows best.
