then there is no need to learn the entire quraan or to even read it during ramadaan,etc all you have to 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.
Firstly: there follow some of the ahaadeeth narrated from the Prophet (peace and blessings of Allaah be upon him) which state that Soorat al-Ikhlaas (Qul Huwa Allaahu Ahad) is equivalent to one-third of the 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 of the 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 is equivalent to one-third of the 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 will recite 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) came out and recited Qul Huwa Allaahu Ahad, then he went in. They said to one another, Perhaps there has been some news from heaven 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 was going 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 it more reward for simple deeds. It is strange that with some people, instead of 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 of the Qur’aan in reward, but not in terms of being sufficient or taking the place of reading one-third of 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 that there 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.
The Muslim cannot do without the two other issues, which are the rulings and the promises and warnings. His knowledge cannot be complete unless he looks at the Book of Allaah as a whole. The one who stops at Soorat al-Ikhlaas cannot know the other two matters.
Shaykh al-Islam (Ibn Taymiyah – may Allaah have mercy on him) said:
Rewards are of different types, just as wealth is of different types, such as food, drink, clothing, houses, money and so on. If a man possesses one type of wealth, to the value of one thousand dinars, that does not mean that he can do without the other types. Rather if he has wealth in the form of food, he also needs clothing and a place to live, etc. Similarly if it is a type other than money, he still needs other things. If he has nothing but money, he will need all kinds of wealth that are usually needed. In al-Faatihah there are the benefits of praise and du’aa’ which people need, and Qul Huwa Allaahu Ahad cannot replace it in that sense. Although its reward is very great, he cannot benefit from it unless he also recites the Opening of the Book (al-Faatihah) in his prayer. Hence if a person recites only Qul Huwa Allaahu Ahad in his prayer, without al-Faatihah, his prayer is not valid. Even if he recited the whole of the Qur’aan without al-Faatihah, his prayer would not be valid, because the al-Faatihah refers to the basic needs that people cannot do without.
Majmoo’ al-Fataawa, 17/131.
And he said:
The people need the commands, prohibitions and stories that are in the Qur’aan, even though Tawheed is greater than that. Man needs to know what he is enjoined to do and what he is forbidden to do; he need to know what is enjoined upon him and the stories and promises and rewards. These cannot be replaced by anything else, and Tawheed cannot be replaced by these. The stories cannot take the place of the commands and prohibitions, and the commands and prohibitions cannot take the place of the stories. Rather everything that was sent down by Allaah is beneficial and people need it.
If a person recites Qul Huwa Allaahu Ahad, he earns a reward equivalent to the reward of one-third of the Qur’aan, but that does not mean that the reward is of the same kind as that earned by reading the rest of the Qur’aan. Rather he may need the kind of reward that comes from reading the commands and prohibitions and stories, so Qul Huwa Allaahu Ahad cannot take the place of all that.
And he said:
The knowledge that is to be gained by reading the rest of the Qur’aan cannot be gained by reciting this soorah only. So whoever reads the whole Qur’aan is better than one who simply recites this soorah three times in the sense that he earns different kinds of reward, even though the one who recites Qul Huwa Allaahu Ahad earns a reward equivalent to that reward, but it is of one type and does not include all the types that a person needs. This is like a man who has three thousand dinars and another who has food, clothing, accommodation and money equivalent to three thousand dinars. The latter has that which will benefit him in all his affairs, whereas the former needs what the latter has, even though what he has is equivalent in value. Similarly, if he has the finest food, equivalent to three thousand dinars in value, he still needs clothing and accommodation, and weapons and tools that will ward off harm from him, and the like, which cannot be done with food alone.

And Allaah knows best.
