What is the ruling on non-Muslims entering the Masjid?

It is forbidden for Muslims to allow any kaafir to enter al-Masjid al-Haraam [in Makkah] and the sacred areas [al-Haram] around it, because Allaah says (interpretation of the meaning):

“O you who believe! Verily, the Mushrikûn (polytheists) are Najasun (impure). So let them not come near Al-Masjid Al-Harâm (at Makkah) after this year” [al-Tawbah 9:28].

With regard to other Masjids, some fuqaha’ said that it is permissible because there is nothing to indicate that it is not allowed; others said that it is not permissible, by analogy with al-Masjid al-Haraam.

• The correct view is that it is permissible if it serves the interests of sharee’ah or meet a valid need, such as a person hearing something that may invite him to enter Islam, or because he needs to drink water in the mosque, or the like.

• This is because the Prophet ( Sallallahu alaihi wa sallam ) tied up (his prisoner) Thamaamah ibn Athaal al-Hanafi in the mosque before he became Muslim, and the delegations of Thaqeef and the Christians of Najraan stayed in the mosque before they became Muslim.

• There were many benefits offered by doing this: they could hear the speeches and sermons of the Prophet (Sallallahu alaihi wa sallam), see people praying and reciting Qur’aan, and other benefits that are gained by those who visit the mosque.
