A: There is nothing wrong with advance treatment if there is a fear that a disease may occur, because of the presence of an epidemic or other factors which may cause disease. There is nothing wrong with getting medicine to ward off expected diseases. The Prophet (peace be upon him) said in the Sahih (authentic) Hadith: "He who eats seven dates of Madinah in the morning will not be harmed by Sihr (sorcery) or poison." This is a way of warding off diversity before it occurs. So, if there is a fear of sickness and a person is vaccinated against an infection that is present in the country or elsewhere, there is nothing wrong with that, because it is a kind of protection. As the current disease is to be treated by medicine, so the feared disease is to be treated as well. However, it is not permissible to wear or hang up amulets against sickness, the jinn, or the evil eye, because the Prophet (peace be upon him) forbade that and explained that this is a kind of minor Shirk (associating others in worship with Allah), so it must be avoided.
