Eating animals slaughtered by one who observes the pillars of Islam but wears amulets

Q 2: Is it permissible to eat from the meat of the animals slaughtered by those who testify that La ilaha illa Allah (there is no god but Allah), perform Salahs (Prayers), pay Zakah (obligatory charity) and perform Hajj (Pilgrimage) but wear amulets with or without Ayahs (Qur'anic verses)?

A: If the amulets contain Qur'an or some of the Names and Attributes of Allah, then it is permissible to eat from the meat of the animals slaughtered by those who wear them. But if the amulets contain any other writing, then reference should be made to the report narrated by Ahmad and Abu Dawud on the authority of Ibn Mas`ud (may Allah be pleased with him) who said: "I heard the Messenger of Allah (peace be upon him) saying: Spells, charms, and love-potions are acts of Shirk 'associating others in worship with Allah'". This is a proof that such acts are forms of Shirk. The meat of animals slaughtered by those who commit these acts is impermissible to eat, for they are Mushriks (people who associate others in worship with Allah) if they believe that spells may benefit or harm them. If they believe that they are just causes and Allah is the Beneficent and the One Who can cause harm, wearing them is considered an act of Al-Shirk-ul-Asghar (minor form of associating others in worship with Allah). You may abandon sharing their food to discourage them from wearing them.
