And when they meet those who believe, they say, "We believe"; but when they are alone with their evil ones, they say, "Indeed, we are with you; we were only mockers."

Wa idha • and when

This is the third verse which starts from wa itha. All these verses are about the problems of hypocrites that make Allah angry with them. The Quran uses the same pattern to describe their problems.

Aladhina Amanu • Those who believe

There is another point to be noticed that the Quran here uses the verb form "those who believe" instead of using the noun muminoon "believers". The verb form makes it more eloquent in this place and context because it also gives the detail about tense ( past tense) and their ongoing active quality of faith.

Ila shaitanihim • Toward devils

The Quran doesn't say 'alone with devils' but 'alone to the devils', which is more eloquent because it indicates they seek their devils and they convey their mockery to them, not merely being with them.

Inna Ma'akum • Indeed with you

There's a linguistic point to be noticed here that they say normally to believers that we believe and the word inna is not used there but with devils, they use the word " inna. It's because believers don't know they have ties with their devil leaders so they just make sure in common words. But the devil leaders know they have ties with believers so they use Inna to make sure we are still with you by heart and they were just pretending to be believers.

And when it is said to them, "Believe as the people have believed," they say, "Should we believe as the foolish have believed?" Unquestionably, it is they who are the foolish, but they know [it] not.

This verse is one of the linguistic masterpiece, Quran uses exact skeleton of verse 11-12 in this verse but only inward text is changed. Such repetition of skeleton but change in central text creates text body that reinforces the central idea instead of outward text and such repetition also make Quran easy to understand and memorize.

Wa Idha qeela lahum • and When it is said to them

This exact wording is repeated in verse 11 with same words but what changed here is the next central text is different before it was said to them " do not spread corruption" now it's said to them "believe as others believe". See linguistic miracles of Quran of this skeleton in previous verses.

Qaalu • They say

This word "qaalu" is also in the skeleton. In previous verse 11 they replied that they are reformers and in this verse they reply that others are fools.

Ala innahum hum • Beware certainly they themselves

Now Allah replies to them and it uses same structure of verse 12 in which Allah replies to them that they are corrupters. In this verse Allah replies that they are fools. The repetition of hum and Ala is used for emphasis and Altertness because God himself is telling them the truth. See linguistic miracles of Quran of this skeleton in previous verses.

La yalamoon • They do not know

In previous verse it was said that they do not perceive but in this verse it's said that they do not know. Both words are perfect for each context because deception or corruption is perceived through insight that they lack and who's fool is known that they know not.

Beware, it is they who are the corrupters, but they perceive it not.

Ala • Beware

This verse powerfully rejects the claims of hypocrites in a rhetorical way against their saying "we are only reformers". The first word ala means beware which is mentioned to warn and alert others that next news is very important.

Inna • indeed

The word INNA is used here for more emphasis that there is no doubt in next phrase that's About to be mentioned and it's completely neutral.

Hum • They

The word hum is mentioned twice which adds further stress and exclusivity to show utmost importance.

Hum ul mufsidoon • They are corrupters

This phrase uses previous verse structure and words to keep Quranic language easy to understand and accessible for everyone. Quran used this phrase for believers that "Hum ul muflihoon" they are successful. The word F-S-D is also used in previous verse where it was shown as opposite to S-L-H. The word Al before mufsidoon means Quran is referring to specific group of hypocrites

Lakin • But

After so much emphasis Quran uses the word lakin. A reader might have some assumption that hypocrites are labeled emphatically corrupters then they must be aware of it. The word lakin which connects to next sentence removes this assumption.

La Yashuroon • perceive not

Here Quran doesn't say that they do not understand "Ma Yalmoon" or any other word. It's because The word yasharoon means that the hypocrites don't have insight which is more severe and strong word than not having knowledge. This word is also used in previous verse to make Quran's language accessible and Universal

And when it is said to them, "Do not cause corruption on the earth," they say, "We are but reformers."

Qeela lahum• It is said

Quran used passive voice sentence here that it's said to them, but it doesn't say qaala lahum (someone told them). Quran used passive sentence to keep the audience focus on the next sentence not to the one who told them and to keep verse short and rhetorically beautiful.

Tufsidu • imbalance or corruption

Quran in this verse uses the root word F-S-D which means to cause imbalance and in next sentence it uses the opposite word for their claim. The word S-L-H is exact opposite of F-S-D which means to cause balance or ordering things.

Ard • Earth

Quran could've said do not spread corruption in country or tribe but it used the word earth/land which is more common and more vast word and makes this verse Universal and easy to understand Quran's Arabic as well.

Nahnu Muslihun • We are balance maker

This is in human psychology that to defend himself he will tell positive logical points about that subject to dismiss the claim and he will rationalize why a that point doesn't matter.

In their hearts is disease, so Allāh has increased their disease; and for them is a painful punishment because they [habitually] used to lie.

Fi • In

Quran uses the word Fi to show that the disease of doubts and hypocrisy are deep rooted inside the hearts of hypocrite whereas it used the word Ala (on) for sealing on their hearts.

Qulubihim • Their hearts

Methodology Of This interpretation Explained In Article 2:7, in summarization we concluded that heart helps us to feel emotions and when Quran mentions about heart it mainly means heart-brain connection because if Quran had mentioned only mind then it may not have described the emotional side of human being and mind refers to only logical & analytical reasoning which is also mentioned in Quran but not here. By mentioning hearts Quran make it understand to arab audience and intellectual people of modern times that feeling is felt by hearts and heart-brain connection leads our motivations. The Quran describes here the diseases like doubt (feeling suspicious) and arrogance (feeling of superiority) etc which are felt in our heart and heart-brain connection make us feel and work upon it.

Mardun • Disease

Quran uses the perfect word here, it could've said that in their hearts is darkness or something else but it used the word disease, because the characteristic of disease is that it doesn't remain stable if it's untreated it increases and worsens overtime just likee hypocrite increase in their disease of doubts by hiding their identity.

fazadahum u Allahu • Allah lets increase

Quran used the word disease which have characteristic to increase and here Allah defines that word. This also shows it's natural growth that if a person has a disease it will increase and same like the disease of arrogance and doubts also increases if it's untreated.

Azabun Aleem • Painful Punishment

The beauty of Quran is that it's perfected in each way , Quran could've only said "for them is punishment " but it said adabun Aleem with the adjective Aleem. which makes very perfect combination for Listeners. For hypocrite the punishment was not only at the day of judgement but also in this world because if a person hides or lies it naturally creates anxiety and stressful life.

yakthiboon • they used to lie

The last word in this verse is perfected in poetic style. Previous and next verses also end in the same manner. For example previous verse ends with yashuroon and next verse ends with muslihoon even letters in words have same number.

Quran2:7: Allāh has set a seal upon their hearts and upon their hearing, and over their vision is a veil. And for them is a great punishment.

Scientific Explaination:

Methodology Of This interpretation Explained In Article 2:7

Sealing of heart means here that a person heart stop feeling about Allah and his words and this person's heart doesn't become soft when he hears about God. We discussed scientifically in the article 2:7 that how heart helps us to feel and this feeling comes from the whole body and felt in the heart and it effects the brain. There are two main types of feeling in heart , first is when the heart produces smooth rythm it's when person do good action (love or being compassionate) and feels this and second is irregular rythm of heart it's when he is angry or in stress. Believers and Disbelievers heart can be categorized in two types, believer heart finds comfort and his heart rythms becomes smooth when Allah is mentioned and person physically feel this in his chest too. The disbeliever heart doesn't find this comfort and his heart do not become smooth due to rooted feeling of superiority and doubts. These doubts are also created by him due to ego and stubborn.

Psychology Of A Disbeliever:

Initially when person hears about Allah's message if his heart have ego or worldly attachments then he will interpret it as a danger to his current belief or worldly attachments or his sense of superiority. Accepting the new idea would mean admitting "I was wrong " making him uncomfortable and threat to his ego or worldly attachments or his current beliefs. That's why his brain will console him that he's on right path by creating arguments and he will try to convince himself to save his kingdom. At this point his brain makes a lot of doubts in his mind that he is right and when next time he hears the same message he doesn't become uncomfortable and without arguing he thinks that it's nonsense and everything passes over brain which makes him not to think or hear anything. At this point his heart doesn't feel anything neither his brain thinks nor his ears hear nor his eyes see. The situation can be little different for different personalities but this is the end that a Disbelieve reaches and Allah knows best.
