In Jainism, "nindha" (also spelled as "ninda") means criticism, condemnation, or slander. It refers to speaking ill of others, finding faults, or disrespecting others through words or actions.

According to Jain teachings, nindha is considered a form of asatya (falsehood) and himsa (violence) through speech. It generates negative karma, as it causes harm and disturbance to others. Jain scriptures advise followers to practice right speech (samyak vāch), which includes:

• Avoiding nindha (criticism or slander)
• Speaking truthfully, kindly, and beneficially
• Avoiding gossip and divisive speech

By abstaining from nindha, one practices ahimsa (non-violence) and cultivates virtues like forgiveness, humility, and compassion, which are central to Jain ethics.
