The Great Verse on the Punishment of Allah

“The punishment of your Lord will surely come” (Quran 52: 7).

• Shaykh al-‘Usaymin (may have mercy on him) said:

That is, the punishment of Allah, which He promised to fulfill, must necessarily come. This, by Allah, is a great influencing (touching) phrase. However, it only affects a soft heart, with a softness similar to the softness of butter or even more. And a hard heart does not pay attention to her, and she passes by, while it (i.e the heart) is like a stone. “
