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 9,8){ يَوْمَ تَكُوْنُ السَّمَآءُ كَالْمُهْلِ … : ’’ كَالْمُهْلِ ‘‘} That is, the sky will become like molten copper (red and hot, splitting apart). (See Rahman: 37) {’’اَلْعِهْنُ‘‘} Wool, that is, the mountains will become as light as carded wool and will begin to fly away. See Surah Ta-Ha (105) and Qari'ah (5).
