The ruling on wearing a device that repels mosquitoes as a precaution

Question:
The questioner says: Honorable Shaykh, there is now available in pharmacies a device worn on the wrist, the size of a pager, which contains a battery. Its benefit is that it prevents mosquitoes from biting you within a five-meter radius in every direction. Is it permissible to wear it as a precaution against Rift Valley fever? I ask for clarification.

Answer:
Doctors ask about this. If it is true that it repels mosquitoes, because it contains a substance that drives them away, then there is no harm in using it, as it is a form of precaution, like the creams they use now. One applies it to the skin and it protects him from mosquitoes. This is a form of precaution, and there is nothing wrong with it. If this is established, it is a form of precaution. Yes. And this indicates the weakness of people nowadays; they are afraid of mosquitoes. Being afraid of mosquitoes now indicates the weakness of people. Do they feel safe from them? Yes.
