لَا تُظْهِرِ الشَّمَاتَةَ لِأَخِيكَ فَيَرْحَمَهُ اللَّهُ وَيَبْتَلِيكَ
Do not show malicious delight at your brother’s misfortune, lest Allah show him mercy and test you.
Source: الترمذي
لَا تُظْهِرِ prohibits displaying something. الشَّمَاتَةَ is malicious delight in another person’s misfortune, failure, or humiliation. In فَيَرْحَمَهُ, هُ refers to the person suffering; in وَيَبْتَلِيكَ, كَ refers to the person being addressed.
One need not approve of another’s error, yet gloating over their suffering remains a moral fault. No one can assume complete immunity from hardship. The narration encourages humility, compassion, and a sincere desire to see wrongs corrected.
