Do not sell water; be generous with basic necessities; strive for righteousness according to Islamic teachings.

This hadith is about the prohibition of selling water. It was narrated by Abu Minhal that he heard Iyas bin 'Abd Muzani say that he heard the Messenger of Allah forbid selling water. This hadith teaches us to be generous and not to take advantage of people in need, especially when it comes to basic necessities such as water. We should not try to make a profit off something that is essential for life, but instead give it away freely or at least at a reasonable price so everyone can access it. Furthermore, this hadith also teaches us about being mindful and aware of our actions as Muslims; we should always strive to do what is right according to Islamic teachings even if no one else is watching or knows what we are doing.
