Tafsir al-Quran al-Karim is a 4-volume Quran commentary by Hafiz Abdus Salam bin Muhammad Bhutvi, a renowned Salafi (Ahl al-Hadith) scholar and Sheikh ul-Hadith from Pakistan. Based on over 45 years of teaching and research, this tafsir follows the methodology of Tafsir bil-Ma'thur — interpreting the Quran through authentic Hadith, statements of the Companions, and the understanding of the early generations (Salaf). It is distinguished by its complete avoidance of Israeliyyat (Judeo-Christian narratives) and unverified reports. The tafsir is originally written in Urdu, translated to English by tohed.com.

(Ayah 14) ➊ {كَلَّا بَلْ رَانَ عَلٰى قُلُوْبِهِمْ …:’’ كَلَّا ‘‘} "Never!" The meaning is that the reason for this denier's rejection of the verses is not that these are tales of the ancients or that there is any doubt about their truth, but rather his evil deeds have overcome his heart in the form of a black rust, so that neither does he see truth as truth nor falsehood as falsehood. Just like the Orientalists and the deniers of hadith, the previous deniers were also in this state: if a new thing came in the Quran, they would say: « مَا سَمِعْنَا بِهٰذَا فِيْۤ اٰبَآىِٕنَا الْاَوَّلِيْنَ » [ القصص : ۳۶ ] "We have never heard this from our forefathers." And if that thing was present in the previous books, they would say it was stolen from there, that is, {’’ اَسَاطِيْرُ الْاَوَّلِيْنَ ‘‘} that these are tales of the ancients. «قٰتَلَهُمُ اللّٰهُ اَنّٰى يُؤْفَكُوْنَ» [ التوبۃ : ۳۰ ] "May Allah destroy them, how they are deluded!"

{ رَانَ عَلٰى قُلُوْبِهِمْ: ’’ أَيْ رَكِبَهَا كَمَا يَرْكَبُ الصَّدْأُ وَ غَلَبَهَا‘‘} (Zamakhshari) "That is, it has covered their hearts and prevailed over them just as rust covers." The subject of {’’ رَانَ ‘‘} is {’’ مَا كَانُوْا يَكْسِبُوْنَ ‘‘}, meaning that what they used to earn has become rust and has covered their hearts. The characteristic of sin is that if it is committed repeatedly and one does not repent, it engulfs the entire heart. It is narrated from Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: [ إِنَّ الْعَبْدَ إِذَا أَخْطَأَ خَطِيْئَةً نُكِتَتْ فِيْ قَلْبِهِ نُكْتَةٌ سَوْدَاءُ فَإِذَا هُوَ نَزَعَ وَاسْتَغْفَرَ وَ تَابَ سُقِلَ قَلْبُهُ وَ إِنْ عَادَ زِيْدَ فِيْهَا حَتّٰی تَعْلُوَ قَلْبَهُ وَهُوَ الرَّانُ الَّذِيْ ذَكَرَ اللّٰهُ: «كَلَّا بَلْ رَانَ عَلٰى قُلُوْبِهِمْ مَّا كَانُوْا يَكْسِبُوْنَ » ] [ ترمذي، تفسیر القرآن، باب و من سورۃ ویل للمطففین : ۳۳۳۴ ] "When a servant commits a sin, a black spot is placed on his heart. If he refrains and seeks forgiveness, his heart is cleansed. But if he repeats the sin, the spot is increased, until that black spot overcomes his entire heart. This is the 'raan' which Allah, the Exalted, has mentioned: « كَلَّا بَلْ رَانَ عَلٰى قُلُوْبِهِمْ مَّا كَانُوْا يَكْسِبُوْنَ » 'Never! Rather, what they used to earn has covered their hearts as rust.'" This hadith is Hasan Sahih.

3. That is, this Quran is not stories, as the disbelievers say and think. Rather, it is the word of Allah and His revelation which was sent down to His Messenger through Jibreel ؑ the trustworthy.

4. That is, their hearts do not believe in this Quran and divine revelation because their hearts have been covered due to the abundance of sins and have become rusted. This rust is the blackness of sins which, due to continuous sinning, covers the heart. In the hadith it is stated: "When a servant commits a sin, a black dot appears on his heart. If he repents, that blackness is removed, and if instead of repenting, he continues to sin, that blackness increases until it covers his entire heart. This is the rust mentioned in the Noble Quran." (Tirmidhi, Chapter: Tafsir of Surah Al-Mutaffifin, Ibn Majah, Book of Zuhd, Chapter: Mention of Sins. Musnad Ahmad 297/2)

14. No! Rather, the rust of their evil deeds has covered their hearts. [9]

The Black Spot on the Heart Due to Sinning:

The real issue is not that there is any doubt or uncertainty in Our verses, nor that they lack the power to influence. Rather, the real matter is that by repeatedly committing sins, their hearts have become distorted and rusted. They no longer have the ability to distinguish between truth and falsehood. The explanation of this verse is given in a hadith as follows: Sayyiduna Abu Hurairah ؓ says that the Prophet ﷺ said: When a servant commits a sin, a black spot appears on his heart. Then if he leaves the sin, seeks forgiveness, and repents, his heart is cleansed. But if he commits the sin again, the spot increases until it covers the heart. And this is the rust that Allah Almighty has mentioned in this verse. [ترمذي : ابواب التفسير]
