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.

6. And when the seas are set ablaze [7],

The Fate of the Seas on the Day of Judgment:

In ﴿سُجِّرَتْ﴾ and ﴿سجر﴾, there is the meaning of something being filled and of mixing or turbulence within it. By ﴿البحر المسجور﴾ is meant the sea that is both full and, due to the surge of turbulence, is also boiling over. The meaning of ﴿سجّرالتنّور﴾ is to fill an oven with fuel and heat it so that the fire blazes with full intensity, and "sajoor" refers to the fuel with which the oven is heated. Thus, anything that is thrown into the oven to intensify the fire is called "sajoor." Now, consider that water is a combination of two gases: oxygen and hydrogen. Hydrogen itself is a flammable gas that ignites immediately when exposed to fire, and oxygen helps the fire to blaze. It is a marvel of Allah's power that when these two gases are chemically combined, the resulting water has properties completely opposite to those gases and immediately extinguishes fire. On the Day of Judgment, the water of the seas will be converted back into these two gases. Then, fire will be set to them, and eventually, they will dry up.
