چھپکلی کو مارنے کی حدیث
Lizards are a creation of Allah and they play an important role in the ecology of cities and human habitat. They feed on a variety of insects, like mosquitoes, moths, flies, and spiders. By preying on these insects, they help control their populations. They are also a part of food chain for other bigger animals and birds. So there is no need to kill lizards unnecessarily. This narration is most likely fabricated or weak. And unnecessary cruelty to animals is not a likeable trait.
