harm and injury or not, and whether or not it is done with the permission of the governing authority in the town.
The correct view is otherwise: he may install waterspouts, provided that they cause no harm. This was the people’s customary practice even during the time of the Prophet ﷺ: waterspouts would extend over the street (1). Shaykh al-Islam said that seeking the ruler’s permission is contrary to the sunnah, and that the established sunnah is that people extend their waterspouts without seeking the ruler’s permission. This is the correct view and the practice followed to this day.
Thus, the sound view is that one may install a waterspout, on condition that it causes no harm. Harm would be for the waterspout to hang so low that it strikes the head of a rider or the like.
If someone were to say: “Surely there must be harm in the waterspout, since when rain comes, it will pour down upon passersby?”
The reply is: First, this does not happen all the time.
Second, during heavy rainfall, when water pours from the waterspouts, people will be indoors and will not go out. This is a tolerable harm in light of the benefit it brings to people.
