There is a Christian person who stands among Muslims in rows of Salah (Prayer).
He used to imitate worshippers in their moves and learnt some Ayahs (verses of the Qur'an). Many trials have been carried out to make him pronounce Shahadah (Testimony of Faith), but he completely refused. What is the ruling on letting him participate in congregational Salah?
(Part No. 12; Page No. 257)
It is permissible to permit Christians to stand in rows of Salah among Muslims. We are not required to expel them from it because staying among Muslims and watching the acts of worship is from the public interest. Moreover, permitting them to stand in Muslim rows attracts them to Islam and gives a good reputation to Islam and Muslims.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
