Will the Muslim be rewarded for refraining from sin whatever the case?

Praise
be to Allah

Firstly:

If someone
refrains from committing a sin, then he must be refraining for one of the
following reasons:

i.                   

He refrains from
sin out of fear of Allah. He will be rewarded for refraining from that sin,
because the Prophet (blessings and peace of Allah be upon him) said in a
hadith qudsi [that Allah said to the angels]: “… and if he gives it (the bad
deed) up for My sake, then record it for him as one good deed…” Narrated by
al-Bukhaari (7501).

ii.                 

He refrains from
sin so as to show off to people, and seeking their praise. He will not be
rewarded for refraining from it; rather he may be sinning thereby, because
refraining from sin is an act of worship, and acts of worship should only be
done for Allah.

Ibn Rajab said:
But if he thinks of committing a sin then refrains from doing it out of fear
of people, or to show off to them, then it was said that he will be punished
for refraining from sin with this intention, because giving precedence to
fear of people over fear of Allah is forbidden. Similarly, intending to show
off to people is also forbidden. So if that (showing off) is combined with
refraining from sin for that purpose, he will be punished for refraining.

Ibn al-Qayyim
al-Jawziyyah (may Allah have mercy on him) said: … If someone refrains from
(sin) for the sake of something other than Allah and not for the sake of
Allah, he will be punished for refraining for the sake of something other
than Allah, just as he would be punished for doing it for the sake of
something other than Allah. This restraint and refraining is one of the
deeds of the heart, and if it is done as an act of worship for something
other than Allah, then he deserves punishment.

iii.               

He refrains from
sin to avoid embarrassment before people. There is no sin on him in this
case for refraining; however, he may be rewarded for refraining if that was
done for a shar‘i purpose that Allah, may He be exalted, loves, such as if
he refrained from sin lest his action lead to aspersions being cast upon the
du‘aat [those who call people to Allah] and religious people.

Ibn al-Qayyim
(may Allah have mercy on him) said – differentiating between this case and
the previous one: If it is said: how can he be punished for refraining from
sin to avoid embarrassment before people and to preserve his status among
them, and for fear that they turn against him, when Allah, may He be
glorified, does not condemn that or disallow it?

The answer is:
undoubtedly he will not be punished for that. Rather he may be punished for
seeking to draw closer to people by refraining from that sin and showing off
to them thereby, so that they think that he refrained from it for fear of
Allah and knowing that He is watching, when in reality that was not the
case. So there is a difference between refraining from sin in order to draw
closer to people and to show off to them, and refraining from sin to avoid
embarrassment before them, and fear of their harm and that he may lose
respect in their eyes. In this case he will not be punished for it; in fact
he may be rewarded for it, if he did that for a purpose that Allah loves,
such as upholding the status of the caller to Allah, and so that people will
continue to listen to him and benefit thereby, and so on.

iv.              

He refrains from
sin because he has no interest in it, and his refraining is not out of fear
of Allah or for the sake of any of His creation. In this case he will not be
rewarded, and he is not sinning.

Shaykh al-Islam
Ibn Taymiyah (may Allah have mercy on him) said: This is the one who thinks
of committing a bad deed, then he refrains from it either out of fear of
Allah, or for some other reason. If he refrains from it out of fear of
Allah, Allah will record an entire hasanah with Him for him, as is clearly
stated in the hadith, and as it says in another hadith: “Record for him one
hasanah, for He only refrained from it for My sake.”

Or he refrained
from it for some other reason, in which case no bad deed will be recorded
against him, as it says in another hadith: “If he does not do it, nothing
will be recorded against him.” Thus the meanings of the different reports on
this topic may be reconciled.

Secondly:

Acts of worship
are not accepted from the Muslim unless two conditions are fulfilled:

i.                   

The intention (niyyah)
should be sincerely for the sake of Allah, may He be exalted, alone. This
means that in his words and deeds, both outward and inward, the individual
is seeking Allah, may He be exalted, to the exclusion of all others.

ii.                 

It must be in
accordance with the shar‘ that Allah, may He be exalted, has enjoined and
has decreed that He is not to be worshipped except as He has prescribed.
That is attained by following what the Prophet (blessings and peace of Allah
be upon him) brought and not going against it, and not introducing any new
acts of worship or new styles of performing acts of worship that are not
proven to be soundly narrated from the Prophet (blessings and peace of Allah
be upon him).

The evidence for
these two conditions is the verse in which Allah, may He be exalted, says
(interpretation of the meaning):

“So whoever
would hope for the meeting with his Lord – let him do righteous work and not
associate in the worship of his Lord anyone”

[al-Kahf 18:10].

Based on that,
if a child prays for fear of his father or seeking to please his father, and
does not intend alongside that to please Allah, then his prayer is not
accepted, because prayer is an act of worship, and worship can only be done
for Allah.

But if he
intends in his prayer – which is usually the case – to please Allah, then to
please his parents as a secondary objective, then in this case his prayer
will be accepted, in sha Allah.

And Allah knows
best.
