Praise be to Allaah.
The scholars are agreed that the benefits of du’aa’, praying
for forgiveness, giving charity and Hajj reach the deceased.
With regard to du’aa’ and praying for forgiveness, Allaah
says (interpretation of the meaning):
“And those who came
after them say: ‘Our Lord! Forgive us and our brethren who have preceded us
The Prophet (peace and blessings of Allaah be upon him)
said: “Pray for forgiveness for your brother and ask that he be made
steadfast, for now he is being questioned.”
And he (peace and blessings of Allaah be upon him) said:
“When you offer the (funeral) prayer for the deceased, then make du’aa’
sincerely for him.”
With regard to charity, it was narrated in al-Saheehayn
from ‘Aa’ishah that a man said to the Prophet (peace and blessings of
Allaah be upon him): “My mother died suddenly and she did not leave a will,
but I think that if she could have spoken she would have given in charity.
Will she have a reward if I give in charity on her behalf?” The Prophet
(peace and blessings of Allaah be upon him) said: “Yes.” Narrated by
al-Bukhaari, no. 1388; Muslim, no. 1004.
And it was narrated by al-Bukhaari from Sa’d ibn ‘Ubaadah
that his mother died when he was absent, and he said: “O Messenger of
Allaah, my mother has died when I was absent. Will it benefit her if I give
in charity on her behalf?” He said: “Yes.” He said: “I ask you to bear
witness that my garden that bears fruit is given in charity on her behalf.”
Narrated by al-Bukhaari, 2756.
With regard to Hajj, the Prophet (peace and blessings of
Allaah be upon him) said to one who asked him about Hajj: “Don’t you think
that if your mother had a debt, you would pay it off for her?” She said:
“Yes.” He said: “A debt owed to Allaah is more deserving of being paid off.”
Narrated by al-Bukhaari, 6699; Muslim, 1148.
From the above you will know that giving charity on behalf of
the deceased will benefit him and its reward will reach him.
There is a da’eef (weak) hadeeth about offering prayer on
behalf of the dead. Imam Muslim mentioned in his introduction to his
Saheeh that ‘Abd-Allaah ibn al-Mubaarak regarded this hadeeth as weak,
then he said:
There is no difference of opinion concerning giving charity
(i.e., on behalf of the dead). End quote.
His words “There is no difference of opinion concerning
giving charity (i.e., on behalf of the dead)” means that this hadeeth is not
to be taken as evidence. But whoever wants to honour his parents, let him
give charity on their behalf, for (the reward of) charity will reach the
deceased and benefit them, and there is no difference of opinion among the
Muslims concerning this point. This is the correct view. With regard to the
report narrated by the qaadi Abu’l-Hasan al-Maawardi al-Basri al-Faqeeh
al-Shaafa’i in his book al-Haawi from some of the scholars of
al-kalaam, that no reward can reach the deceased after his death, this is a
view that is definitely wrong and is clearly contrary to the texts of the
Qur’aan and Sunnah and the consensus of the ummah, so no attention should be
paid to it. With regard to praying and fasting on behalf of the dead, the
view of al-Shaafa’i and the majority of the scholars is that the reward for
that does not reach the deceased, unless it is a fast that was obligatory
for the deceased, so his heir or someone to whom the heir gives permission
makes it up on his behalf. Two views concerning this were narrated from
al-Shaafa’i, the better known of which is that it is not valid; the more
correct view according to the later Shaafa’i scholars is that it is valid.
With regard to reading Qur’aan, the well-known view of the
Shaafa’i madhhab is that the reward for that does not reach the deceased.
Some of his companions said that its reward does reach the deceased. Some of
the scholars were of the view that the reward of all acts of worship –
prayer, fasting, reading Qur’aan, etc – reaches the deceased… Then al-Nawawi
mentioned that the reward for du’aa’, charity and Hajj reaches the deceased,
according to scholarly consensus.
It says in Tuhfat al-Muhtaaj (7/72):
The deceased can benefit from charity given on his behalf,
which includes a waqf of a Mus-haf etc, or digging a well, or planting a
tree, whether he does that during his lifetime or it is done by someone else
on his behalf after his death.
With regard to the best ways of benefiting your father, you
should make a lot of du’aa’ for him. Allaah says (interpretation of the
“and say: ‘My Lord! Bestow on them Your Mercy as they did
bring me up when I was young’”
And the Prophet
(peace and blessings of Allaah be upon him) said: “When a person dies, all
his good deeds come to an end except three: ongoing charity, or beneficial
knowledge, or a righteous child who will pray for him.”
With regard to charity, the best things on which charity may be spent are jihad for the sake of Allaah, building mosques, and helping seekers of knowledge by printing books for them or giving them money that they need. And Allaah knows best.
