Verse: "No indeed! Rather, what they used to earn has covered their hearts with rust"
Reflection:
"Rayn" in Arabic means the rust that covers something and obscures its shine. Here Allah describes the hearts of the deniers upon which sins have accumulated until they lost their ability to perceive truth.
The prophetic hadith explains this verse:
The Prophet said: "When the believer commits a sin, a black dot appears in his heart. If he repents, desists, and seeks forgiveness, his heart is polished. If he persists, it increases until it covers his heart — that is the rust (rayn) that Allah mentioned." [Al-Tirmidhi and Ibn Majah]
The chain of the heart's deterioration:
- First sin → small black dot
- Repeated sins → the dot expands
- Persistence without repentance → rust covers the heart
- Complete rust → the heart neither sees truth nor is affected by it
Lesson: Seeking forgiveness is not a verbal ritual — it is the polish of the heart. Do it abundantly every day before the rust accumulates.
Question: How does "rayn" form on the heart according to the hadith?
Answer: Each sin places a black dot; they accumulate through persistence until they cover the heart. Repentance and seeking forgiveness polish it
