Praying behind someone who makes amulets containing Ayahs or Du`a'

Q 3: Is it permissible to perform Salah (prayer) behind an Imam (the one who leads congregational Prayer) who writes amulets? I must say that this man does not write these amulets for magic purposes, but for little affairs like headaches, getting newborns to nurse...Etc. (Part No. 1; Page No. 324) Please clarify this matter to me, especially that some scholars say that he is considered a Mushrik (one who associates others with Allah in worship), and therefore it is not permissible to perform Salah behind him.

A: It is permissible to perform Salah behind one who makes amulets with Ayahs of the Qur’an or prescribed supplications. However, he should refrain from writing these amulets as it is not permissible in Islam to wear them. If these amulets contain anything involving Shirk (associating others with Allah in His Divinity or worship), then it is not permissible to perform Salah behind the person who makes them. Whoever is aware of its ruling should advise such person that this is an act of Shirk.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
