Islam strongly condemns gossip and backbiting (ghibah) due to their harmful effects, emphasizing:

1. **Prohibition:** Gossip and backbiting are forbidden in the Quran and Hadith, described as sinful behaviors that harm individuals and communities.

2. **Comparison to Eating Dead Flesh:** The Quran equates backbiting to eating the flesh of one’s dead brother, highlighting its severity and repulsiveness.

3. **Harm to Community:** These actions create distrust, spread negativity, and damage relationships within the community.

4. **Encouragement of Positive Speech:** Islam encourages speaking well of others or remaining silent, fostering respect and harmony.

In summary, Islam warns against gossip and backbiting to promote unity, trust, and respect among people.
