Which was revealed in Makkah

بِسْمِ اللَّهِ الرَّحْمَـنِ الرَّحِيمِ

In the Name of Allah, the Most Gracious, the Most Merciful.

Verse [ 104:7] تَطَّلِعُ عَلَى الْأَفْئِدَةِ (that will peep into the hearts). In other words, the fire of Hell will reach their hearts. The basic property of fire is to burn every particle of the things that fall into it. When people are put into the Hell-fire, it will devour every limb and organ of the body until it reaches their heart, but the person will not die. This characteristic of the Hell-fire is especially highlighted in the verse because the fire of this world kills the person even before reaching the heart. The fire of the Hell, on the other hand, will reach the heart in the state of life, and man will experience the torture of the burning of the heart while alive.

Al-Hamdulillah
