Stages of trials for the deceased in his grave and du‘aa’ for him at that time

Firstly: 

In the answer to question no.
157114 we stated that offering du‘aa’ for the
deceased after his burial is Sunnah, because of the report narrated by Abu
Dawood (3221) from the hadeeth of ‘Uthmaan ibn ‘Affaan (may Allah be pleased
with him) who said: When the Prophet (blessings and peace of Allah be upon
him) had finished burying a deceased person, he would stand over him and
say: “Pray for forgiveness for your brother, and ask that he be made
steadfast, for he is being questioned now.” Classed as saheeh by Shaykh al-Albaani
in Saheeh Abi Dawood. 

Secondly: 

Offering du‘aa’ for the deceased Muslims
in general, and for close relatives in particular, is also prescribed in
general terms at any time, without specifying any particular time, because
of the general meaning of the words of Allah, may He be exalted
(interpretation of the meaning):

“And those who came after them say:
“Our Lord! Forgive us and our brethren who have preceded us in Faith”

[al-Hashr 59:10];

And the words of Ibraaheem (peace be upon
him):

“Our Lord! Forgive me and my parents,
and (all) the believers on the Day when the reckoning will be established”

[Ibraaheem 14:41]

And the words of Nooh (peace be upon him):

“My Lord! Forgive me, and my parents,
and him who enters my home as a believer, and all the believing men and
women”

[Nooh 71:28].

And Allah, may He be glorified and
exalted, said to His Prophet Muhammad (blessings and peace of Allah be upon
him):

“and ask forgiveness for your sin, and
also for (the sin of) believing men and believing women”

[Muhammad 47:19].

Secondly: 

Waiting for three days, then offering
du‘aa’ for the deceased for a period of ten days, or twenty or thirty or
forty days, on the grounds that his body goes through a number of stages of
trials during this period, is an act that is contrary to the Sunnah and is a
claim that is devoid of any evidence; it is a fabricated innovation. 

With regard to its being contrary to
the Sunnah: 

That is because the Sunnah is what is
mentioned above, which is to offer du‘aa’ for the deceased at the grave
immediately after his burial. Moreover offering du‘aa’ for the Muslim dead
in general and some in particular is something that is recommended in
general terms, without specifying any particular period or time. 

With regard to what is mentioned being
a mere claim that is devoid of any evidence:
 

That is because these words are not known
in the Sunnah, and we do not know any of the early generations or the imams
and scholars of the Muslims who mentioned that, and we do not know of any
doctors or coroners who have mentioned it in the modern era. 

The idea that the head of the deceased
explodes in the first three days, and his stomach explodes after ten days,
and his entire body explodes after forty days, is a false notion and a
fabricated claim for which there is no evidence. Perhaps this idea is the
basis for the innovations surrounding the fortieth day after death, when
tents are set up, and people come to offer condolences, and the reciter
recites the Qur’an. The scholars have stated that these acts are innovations
(bid‘ah). 

Ibn ‘Uthaymeen (may Allah have mercy on
him) was asked: 

What is the ruling on observing the
fortieth day after death, during which Qur’an is recited and people gather
to offer condolences? 

He replied: This is one of the innovations
that are practised by some people. When forty days have passed since the
death, they organise a condolence gathering in which people gather at the
house of the deceased, and they read Qur’an and illuminate in the place. In
fact this comes under the heading of renewing grief, which is prohibited. 

End quote from Fataawa Noor ‘ala ad-Darb
(9/2) 

The forty-day commemoration is a pharaonic
custom, as has been explained previously in the answer to question no.
12552 

People have various customs and traditions
in that regard, all of which come under the heading of innovations that are
prohibited. 

Ibn ‘Uthaymeen (may Allah have mercy on
him) was asked: 

When seven days have passed since the
death, the women of the bereaved family go to him in the graveyard, and they
start to weep again. When fifteen days have passed, they repeat the same
action, and again when forty days have passed, they mourn for him for a year
or more, and they do not let children play or be happy. Is this permissible
or not? 

He replied: 

This action is not permissible, because
for women to visit graveyards, if the woman goes out of her house for this
purpose, then she is cursed – Allah forbid. The same applies to morning for
a whole year; it is a reprehensible act that is not permissible. 

End quote from Fataawa Noor ‘ala ad-Darb
(9/2) 

By the same token, if the three-day period
mentioned is also something that people do, whereby they set up tents for
receiving condolences for their loss for three days, during which they
recite Qur’an and receive condolences, this is also an innovation. 

With regard to this sequence of du‘aa’s
and prayers for forgiveness for the deceased being an innovation: 

That is because it is something that has
been introduced, for which there is no basis. We do not know of any of the
Muslim scholars who suggested this, let alone there being any basis for it
in the Sunnah or the acts of the Sahaabah. 

Fourthly: 

With regard to the stages through which
the body passes after burial, this is something that only Allah knows.
Bodies vary in the stages of disintegration, and not all bodies disintegrate
in the same manner or at the same time. We have no need to know about that
or examine the matter. Whether the body disintegrates rapidly or slowly, and
whether the stomach explodes after ten days, or more or less than that,
focusing on this and similar matters is a distraction from that which is
much more important to focus on, which is the state of the soul which is
either in a state of bliss or torment. 

You may find a body that has been buried
for many years but has not disintegrated because of environmental factors,
but the individual is in a state of humiliating punishment. 

This is Pharaoh of whom Allah says
(interpretation of the meaning):

“So this day We shall deliver your
(dead) body (out from the sea) that you may be a sign to those who come
after you”

[Yoonus 10:92]. 

Or you may find that a body has
disintegrated completely, but the individual is one of the martyrs who are
in a state of bliss. 

It was narrated by al-Faakihi in
Akhbaar Makkah (2/351) and Ibn Hazm in al-Muhalla (1/42) from
Mansoor ibn ‘Abd ar-Rahmaan that his mother said: When Ibn az-Zubayr (may
Allah be pleased with him) was crucified, Ibn ‘Umar (may Allah be pleased
with him) entered the mosque – and that was when Ibn az-Zubayr was killed
and crucified. It was said to him: Asma’ bint Abi Bakr (may Allah be pleased
with her) is in a corner of the mosque. He went to her and offered her
condolences and said: These dead bodies are nothing; rather the souls are
with Allah, may He be exalted, so fear Allah and be patient. She said: What
is there to keep me from being patient when the head of Yahya ibn Zakariya
was given to one of the prostitutes of the Israelites?

Its isnaad is saheeh. 

Ibn ‘Umar went to the side of some graves
that had collapsed and looked at one of the graves, where he saw a skull
visible. He instructed a man to cover it with earth, then he said: These
bodies will not be harmed by this dust at all; rather it is the souls that
are being punished or rewarded until the Day of Resurrection.

End quote from Tafseer Ibn Rajab
(2/102) 

The basic principle is that punishment or
bliss in the grave happen to the soul, and the soul may be connected to the
body which thus feels something of that punishment or bliss. 

See the answer to question no.

To sum up: 

The details mentioned in the question
about the disintegration of the body after death is an idea for which there
is no evidence. 

What is mentioned about offering du‘aa’
for the deceased forty days after his death in the manner mentioned is a
reprehensible innovation and it is not permissible to do that. 

And Allah knows best.
