Is it permissible to use amulet? The short answer is…
An amulet is a text containing some verses, hadiths and prayers that people carry with them for purposes such as to be protected against illness, evil eye, and disasters. It is often used wrapped in a protective material.
It is permissible to make dua and recite verses of the Holy Qur’an in order to be protected from fear and the evil eye and recover from some diseases. (Bukhari, Fadha’il al-Qur’an, 9; Ibn Majah, Tibb 35-36). There is no tradition narrated from Prophet Muhammad about writing texts such as verses and duas on somewhere and wearing or carrying them with. However, Abullah ibn Umar informed about Prophet Muhammad’s command of “If one of you scares in sleep, he should say: ‘I seek refuge in Allah’s perfect words from His anger, the evil of His servants, the evil suggestions of the devils and their presence.’ Then nothing can harm him.” and told that Abdallah ibn Amr taught this dua to his children who are at the age of discernment and wrote and made them wear it for his children who were yet at the age of discernment (Abu Dawud, Tibb, 19).
It is indicated in some fiqh books that there are some scholars who see no harm in writing verses from the Holy Qur’an and wearing them by making an amulet (al-Fatawa al-Hindiyya, V, 435). However, it is not permissible to use amulet if it will cause negative situations such as expecting an effect from amulet, perceiving it as a protector, and expecting what should be expected from Allah from an amulet. In this context, we should also be on alert against those who exploit the feelings of people.
