Give away extra resources for free or use them in a way that benefits others without expecting anything in return.

The Prophet Muhammad taught us that it is not permissible to sell surplus water. This means that if someone has an excess amount of water, they should not try to make a profit off of it by selling it. Instead, they should give away the extra water for free or use it in a way that benefits others without expecting anything in return. This hadith teaches us about generosity and kindness towards others, as well as being mindful of our resources and using them wisely.
