The Reassurance of Truth and the Unease of Lying

According to the Hadith إِنَّ الصِّدْقَ طُمَأْنِينَةٌ وَإِنَّ الْكَذِبَ رِيبَةٌ, how do truth and falsehood affect the heart?

Wealth, Eloquence, and Protection from Trials (Hadith 79-88)

• Truth causes unease and lying brings peace
• Truth reassures the heart, while lying produces doubt and worry
• Neither affects the heart
• Both cause anger
