Tafsir Taiseer ul-Quran (Facilitation of the Quran) is a comprehensive Quran commentary by Maulana Abdul Rahman Kilani, a renowned Salafi (Ahl al-Hadith) scholar from Pakistan. Known for his eloquent and accessible writing style, Kilani authored this tafsir with a focus on clarity — making Quranic meanings understandable to the common reader. The tafsir provides detailed historical context for verses related to battles and expeditions, and firmly refutes modernist ideologies using strong scriptural evidence. It is widely regarded as an invaluable resource for understanding the Quran and countering deviant interpretations. The tafsir is originally written in Urdu, translated to English by tohed.com.

On the Day when the earth and the mountains will tremble, and the mountains will become heaps of shifting sand [14].

That is, today the roots of the mountains are firmly embedded deep within the earth. But on the Day of Resurrection, this grip of the mountains will loosen. There will be earthquakes in the earth, and the mountains will also begin to tremble. As a result, the rocks of the mountains will fall upon each other and be shattered into pieces, turning into such soft mounds of sand that feet will sink into them, and if a little sand is placed on top, it will all slip down. It should be noted that in ﴿كَثِيْبًا﴾, the letter "kaaf" is not a particle of comparison, but is part of the root of "kathib" (k-th-b), and "kathib" means a long, wide mound of sand.
