As Salaam mu Alaikum
Is it permissible to allow a non Muslim to perform Salaah in the Masjid.
All relevant information is kindly appreciated.
Wa Alaikum As Salaam,
A non Muslim can enter a masjid to listen to sermons etc., however, there is no benefit for him in performing Salaah. Even if a Muslim wants to encourage him to Islam, he should not ask him to perform Salaah individually by following others. As for asking the non Muslim to join in the congregation, this must not be done at all.
And Allah knows best,
Mufti Waseem Khan
