كَذَٰلِكَ يَطْبَعُ ٱللَّهُ عَلَىٰ قُلُوبِ ٱلَّذِينَ لَا يَعْلَمُونَ ﴿59﴾
Thus does Allâh seal up the hearts of those who know not [the proofs and evidence of the Oneness of Allâh i.e. those who try not to understand true facts that which you (Muhammad صلى الله عليه وسلم) have brought to them].
كَذَٰلِكَ kadhālika Thus
يَطْبَعُ yaṭbaʿu Allah seals
ٱللَّهُ l-lahu Allah seals
عَلَىٰ ʿalā [on]
قُلُوبِ qulūbi (the) hearts
ٱلَّذِينَ alladhīna (of) those who
لَا (do) not
يَعْلَمُونَ yaʿlamūna know

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 59) {كَذٰلِكَ يَطْبَعُ اللّٰهُ … :} That is, those whose hearts are devoid of authentic knowledge and who persistently deny everything out of stubbornness, eventually the result is that they no longer retain the ability to accept the truth.
