The NNB jamiat molvis argue that it is permissible to allow non-Muslims into the Musjid.

Answer

The NNB molvis are immoral traitors who have bartered away the Deen for the miserable objectives of the dunya and the nafs. They are guilty of halaalizing a number of major sins.

It is not permissible for muqallideen to dig Ahaadith from the kutub, submit it to their opinion to formulate masaa-il. The Muqallid has to compulsorily refer to the kutub of Fiqh to ascertain the ruling of the Shariah.

The simple ruling of the Shariah is that even a Muslim without wudhu may not enter the Musjid. What then should we conclude from this? How can a kaafir in the state of janaabat enter the Musjid when a Muslim without wudhu may not enter?

There is tafseer for the Ahaadith you have referred to. There are innumerable Ahaadith on which the fatwa of the Mathhab is not based. It is moronic and satanic for a Muqallid to tear a Hadith from the kutub to cancel a Shar'i hukm.

Ask the morons if it is permissible for a junubi Muslim to sit in the Musjid and engage in Thikr or to just enter the Musjid? Non-Muslims wallow in two types of janaabat - physical and spiritual (kufr). When it is haraam for a Muslim with one type of janaabat to enter the Musjid, how can it be permissible for a non-Muslim with two kinds of janaabat to enter a Musjid. The Qur'aan Majeed explicitly prohibits their entry into a Musjid.
