Answer 4156 item2
then there is no need to learn the entire quraan or to even read it
during ramadaan,etc all you haveto do is to read sura Ikhlas.I think
you made a mistake.Sura Ikhlas is the substance of 1/3 of the
quraan.it is amazing to believe that reading the sura Iklas 3 times
will give you the blessing of reading the ENTIRE quraan,then there is
no point reading the entire Quraan.
Praise be to Allaah.
Firstly: there follow some of the ahaadeeth narratedfrom the Prophet
(peace and blessings of Allaah be upon him) which state that Soorat
al-Ikhlaas (QulHuwa Allaahu Ahad) is equivalent to one-third ofthe
Qur'aan.
Al-Bukhaari (6643) narrated from Abu Sa'eed that a man heard another
man reciting Qul Huwa Allaahu Ahad and repeating it. The next morning
he came to the Messenger of Allaah (peace and blessings of Allaah be
upon him) and told him about that. The man thought that it was too
little, but the Messenger of Allaah (peace and blessings of Allaah be
upon him) said: "By the One in Whose hand is my soul, it is equivalent
to one-third ofthe Qur'aan."
Muslim (811) narrated from Abu'l-Dardaa' that the Prophet (peace and
blessings of Allaah be upon him) said: "Is any one of you unable to
recite one-third of the Qur'aan in one night?" They said, "How could
anyone read one-third of the Qur'aan?" He said, "Qul Huwa Allaahu Ahad
isequivalent to one-third ofthe Qur'aan."
Muslim (812) narrated that Abu Hurayrah said: The Messenger of Allaah
(peace and blessings of Allaah be upon him) said: "Gather together,
for I willrecite to you one-third of the Qur'aan." So those who could
gather together gathered there, then the Prophet of Allaah(peace and
blessings of Allaah be upon him) cameout and recited Qul Huwa Allaahu
Ahad, then he went in. They said to one another, Perhaps there has
been some news fromheaven on account of which he has gone inside (the
house). Then the Prophet of Allaah (peace and blessings of Allaah be
upon him) came out and said, "I told you that I wasgoing to recite to
you one-third of the Qur'aan. Verily it is equivalent to one-third of
the Qur'aan."
Secondly: The bounty of Allaah is immense, and Allaah has bestowed His
bounty upon this ummah and has made up for its short life span by
giving itmore reward for simple deeds. It is strange that with some
people, insteadof this motivating them to do more good, this makes
them apathetic and lazy in doing acts of worship, or they feel that
this bounty and reward is strange and farfetched.
With regard to the meaning of the hadeeth:
There is a difference between jaza' (reward) and ijza' (what is
sufficient). What is making the brother confused is that he does not
see the difference between them.
Jaza' means the reward which Allaah gives for obeying Him.
Ijza' means what is sufficient and takes the place of something else.
Reciting Qul Huwa Allaahu Ahad brings a reward equivalent to reciting
one-third of the Qur'aan, but it does not take the place of reading
one-third of the Qur'aan.
If a person vows – for example – to read one-third of the Qur'aan, it
is not sufficient for him to read Qul Huwa Allaahu Ahad, because it is
equivalent to one-third ofthe Qur'aan in reward, butnot in terms of
being sufficient or taking the place of reading one-thirdof the
Qur'aan.
The same may be said of reciting it three times. If a person recites
it three times in his prayer, that does not mean that he does not have
to recite al-Faatihah, even though he will be given the reward of
reciting the whole Qur'aan.
A similar example is the reward given by the Lawgiver to one who
offers a single prayer in the Sanctuary of Makkah, and that he will
have the reward of one hundred thousand prayers. Does anyone take this
divine bounty to means that he does not have to pray for decades
because he offered a single prayer in the Haram that is equivalent to
one hundred thousand prayers?
Rather this has to do with reward; as for what is sufficient, that is
another matter altogether.
Moreover, none of the scholars has ever said thatthere is no need for
us to read the Qur'aan or that Qul Huwa Allaah Ahad is sufficient and
takes the place of that. The correct scholarly view is that this
soorah has this great virtue because the Qur'aan deals with three
topics: one-third for rulings, one-third for promises and warnings,
and one-third for the Divine names and attributes.
This soorah combines names and attributes.
This is the view of Abu'l-'Abbaas ibn Surayj, and Shaykh al-Islam Ibn
Taymiyah stated that it was good in Majmoo' al-Fataawa, 17/103. :->
