Is leasing a plot of land to erect a mobile phone tower permissible, given the disagreement concerning its harm?

To rule on renting land to telecommunications companies for erecting towers, two matters must be considered: the nature of the company's services, and whether these towers cause harm to those in their vicinity.

If the company provides forbidden services such as music and gambling, then renting to them is considered cooperation in sin, and earning from it is forbidden. However, if its services are free from forbidden things, then the potential harm of the towers is considered.

Specialists have differed on the existence of this harm. The principle is "no harm and no causing harm." However, determining harm is referred to experts. Most health organizations deny the existence of clear harm from these towers to date.

Accordingly, if the leased land does not cause harm to people, crops, or animals, and the company's services are free from forbidden things, then it is permissible to rent it, and there is no objection to the resulting earnings.

The lessor must verify the nature of the company's services and the extent of harm its towers might cause by consulting with experts in their country, taking into account the ongoing research in this field.
