Show kindness and mercy when killing any creature no matter how small or insignificant it may seem .

This hadith is about the importance of showing kindness and mercy even when killing a small creature like a gecko. The Prophet Muhammad ﷺ taught that if someone kills a gecko with the first blow, they will be rewarded with good deeds from Allah. If they kill it with the second blow, they will still be rewarded but less than before. And if they kill it with the third blow, their reward will be even less than before. This teaches us to show mercy and kindness in all our actions, no matter how small or insignificant it may seem to us. We should always strive to do what is right in order to receive rewards from Allah for our good deeds.
