Praise be to Allah (The Glorified and Exalted).
The Heart of the Sinner:
When an individual takes part in sinful behavior, his heart becomes covered with darkness, something unseen to our eyes. This is mentioned in the following hadith:
The Prophet (peace and blessings of Allah be upon him) said, “When a slave commits a sin, a black spot appears on his heart. But if he gives it up, seeks forgiveness and repents, his heart will be cleansed, but if he repeats it, (the blackness) will increase until it overwhelms his heart. This is the “raan” which Allah mentions, “Nay! But on their hearts is the Raan (covering of sins and evil deeds) which they used to earn” [83:14]. [al-Tirmidhi no. 3257; Ibn Majah no. 4234; classed as hasan by al-Albaani in Saheeh Ibn Majah, 3422]. The Prophet (peace and blessings be upon him) had also said the following about the heart, “In the body there is a piece of flesh which, if it is sound, the entire body will be sound, and if it is corrupt, the entire body will be corrupt. It is the heart” [al-Bukhari no. 52; Muslim no. 1599].
If an individual persists in sinful conduct, without repenting or mending their behavior, then their heart may eventually harden against the Truth. This will lead the individual away from the path of Allah, as mentioned in the following verse of the Qur’an:
And Allah (The Glorified and Exalted) Knows Best.
