يَـأَيُّهَا ٱلَّذِينَ ءَامَنُوٓاْ إِنَّمَا ٱلمُشرِكُونَ نَجَسٌ فَلَا يَقرَبُواْ ٱلمَسجِدَ ٱلحَرَامَ بَعدَ عَامِهِم هَـذَا وَإِن خِفتُم عَيلَةً فَسَوفَ يُغنِيكُمُ ٱللَّهُ مِن فَضلِهِ إِن شَآءَ إِنَّ ٱللَّهَ عَلِيمٌ حَيمٌ (٢٨
English translation (Quran Explorer): O ye who believe! The idolaters only are unclean. So let them not come near the Inviolable Place of Worship after this their year. If ye fear poverty (from the loss of their merchandise) Allah shall preserve you of His bounty if He will. Lo! Allah is Knower, Wise.
9:28 translation by YUSUFALI: O ye who believe! Truly the Pagans are unclean; so let them not, after this year of theirs, approach the Sacred Mosque. And if ye fear poverty, soon will Allah enrich you, if He wills, out of His bounty, for Allah is All-knowing, All-wise.
Tafseer by FH:Tawbah 9:28:
In these ayahs as was also noted in the declaration of “Al Barah” in the beginning of Surah Tawbah, Allah Subhanawataala states that after this Hajj and Ummrah of the 9th Hijri mushriks (those who worship other deities than God) are Najas i.e. impure, inside and outside.
Thus they were forbidden from the Kaaba, and Mecca and both these places were designated a place of worship for people who declared the Unity of God and declared Prophet Muhammad to be the Rasool and servant of Allah.
Thus people purified in mind and body were given permission to live and worship in Mecca, all Mushriqs whose who deny Tawheed and that Muhammad PBUH is God s Rassool could no longer enter the precincts of Mecca and the Kaaba.
Does this order extend to all mosques? And the answer is no.
what is the proof of this?:
The proof that non-Muslims are allowed in general mosques is evident by the Sunnah, i.e. the actions of Prophet Muhammad PBUH. He allowed non-Muslims including mushriqeen in the mosques for a purpose.
The most famous episode is about the famous chieftain of the Arabs, who had killed many sahabas and was captured and kept in the mosque for three days. He was treated well by Prophet Muhammad and each day was given the invitation to Islam and he declined, he was then released, he went to a nearby oasis, bathed, cleansed himself and came back and declared shahada and embraced Islam publicly to the chagrin of the non-believers.
Often Non Muslims would come to Rasool Allah to ask questions about the Deen and these meetings were held in the mosque.
