And We will have removed whatever is within their breasts of resentment, (7:43)

Almuntakhab Fi Tafsir Alquran Alkarim

We will delete all that was embedded of bitter ill -feeling from their bosoms and blot out all that lurked in their memories of grudge and hatred so as to make the clouds of the past dissolve in the glorious light .They shall jointly rejoice beyond a common joy, and in the ecstasy of their joy they shall enjoy the blissful rivers flowing beneath them and interpret their feeling of gratitude in words, thus: Praise be to Allah and exalted are His glorious attributes: He guided us to His path of righteousness, and without His guidance we would have missed it and we would have been alienated from His purpose .Indeed His Messengers have brought us illumination and enlightenment and brought the truth which dawned upon us and upon those who, had worshipped stocks and stones earlier. There and then they shall be told: This is Paradise of which you have come into possession by right and divine grant

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(7:43) We shall strip away all rancour from their hearts, *32 and rivers shall flow beneath them, and they shall say: 'All praise be to Allah Who has guided us on to this. Had it not been for Allah Who granted us guidance, we would not be on the Right Path. Surely the Messengers of our Lord did indeed come down with truth.' Then a voice will cry out to them: 'This is the Paradise which you are made to inherit as a reward for your deeds.'  *33

And We will have removed whatever is within their breasts of resentment, meaning

*32). If there develops any rancour or ill-will among good people during the course of their worldly lives, such rancour and will be removed in the Hereafter. Their hearts will be purged of all hostile feelings and they will enter Paradise as cordial friends. They will not feel envious towards those who had formerly been opposed or hostile to them that they share with them the bounties of Paradise. Significantly, 'Ali once recited this very verse and remarked: 'I wish that I and 'Uthman and Talhah and al-Zubayr will be among those about whom God has said: "And We shall take away all rancour from their hearts" ' (verse 43). (See Qurtubi's comments on verse 43 - Ed.)
Reflection on the verse leads one to conclude that out of His mercy, God will first purge the righteous of their blemishes. This will be done before admitting them to Paradise. Thus they will enter Paradise in a state of untainted purity.
*33). This refers to something of a fine and delicate character that will take place in Paradise. Instead of boasting about their virtuous deeds which led them to Paradise, the righteous will thank and praise God profusely and acknowledge His grace and mercy without which they could never have entered Paradise. On the other hand, God will not impress His bounty upon the righteous; He will rather emphasize that Paradise is granted to them by way of compensation for their righteous conduct, that it is the fruit of their hard labour; that it is not like the crumbs of charity but a fair recompense for their striving. The subtlety involved here is further brought into relief by the fact that the above response will not be made by God. It will rather be just announced to them.
What is said above about the Hereafter may be discerned in the attitude of the righteous in the world itself. The wicked and arrogant ones take great pride in their worldly attainments and ascribe them to their own efforts. They firmly, believe that what they have achieved is the fruit of their labour. Swaved by such notions, they continue to act even more haughtily. Conversely the righteous look upon all the bounties which they receive as favours from God. Accordingly, they thank and praise Him out of gratitude. The more they are lavished with worldly favours, the more humble and generous they become. Moreover, they do not suffer from the illusion that their righteousness will certainly earn them their salvation. On the contrary, they consistently repent over their lapses and earnestly turn to God in the hope that He will pardon them out of His grace and mercy. They are always fearful of God's reckoning lest their evil deeds are found to outweigh their good deeds. According to a tradition the Prophet (peace he on him) said: 'Know well that none will he able to enter Paradise by dint of his good deeds.' When asked if that would apply to him as well, the Prophet (peace he on him) replied: 'Yes, in my case as well; unless God covers me with His mercy and favour.' (Bukhari, Kitab al-Riqaq, 'Bab al-Qasd wa a Mudawamah ala al-Amal' - Ed.)

ان کے دلوں میں ایک دوسرے کے خلاف جو کچھ کدورت ہوگی اسے ہم نکال دیں گے اُن کے نیچے نہریں بہتی ہونگی، اور وہ کہیں گے کہ "تعریف خدا ہی کے لیے ہے جس نے ہمیں یہ راستہ دکھایا، ہم خود راہ نہ پا سکتے تھے اگر خدا ہماری رہنمائی نہ کرتا، ہمارے رب کے بھیجے ہوئے رسول واقعی حق ہی لے کر آئے تھے" اُس وقت ندا آئے گی کہ "یہ جنت جس کے تم وارث بنائے گئے ہو تمہیں اُن اعمال کے بدلے میں ملی ہے جو تم کرتے رہے تھے"
