The ruling on watering trees with wastewater
Machine translationRead the Arabic original
Question:
He says: I have a large open area of land in my house, and lemon trees have grown there, and I tend to them. They are watered with wastewater. Is it permissible to eat the fruit from these trees?
Answer:
Wastewater is problematic because it is impure, mixed with impurities. However, if it is treated so that the impurity is reduced and no color or smell remains, then it is permissible to water trees with it. As for the fruit, it is safer to avoid eating it. Yes.
