Rulings of Musyrik entering the mosque

مَا كَانَ لِلْمُشْرِكِينَ أَن يَعْمُرُوا۟ مَسَٰجِدَ ٱللَّهِ شَٰهِدِينَ عَلَىٰٓ أَنفُسِهِم بِٱلْكُفْرِ ۚ أُو۟لَٰٓئِكَ حَبِطَتْ أَعْمَٰلُهُمْ وَفِى ٱلنَّارِ هُمْ خَٰلِدُونَ

It is not for such as join gods with Allah, to visit or maintain the mosques of Allah while they witness against their own souls to infidelity. The works of such bear no fruit: In Fire shall they dwell.

يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓا۟ إِنَّمَا ٱلْمُشْرِكُونَ نَجَسٌۭ فَلَا يَقْرَبُوا۟ ٱلْمَسْجِدَ ٱلْحَرَامَ بَعْدَ عَامِهِمْ هَٰذَا ۚ وَإِنْ خِفْتُمْ عَيْلَةًۭ فَسَوْفَ يُغْنِيكُمُ ٱللَّهُ مِن فَضْلِهِۦٓ إِن شَآءَ ۚ إِنَّ ٱللَّهَ عَلِيمٌ حَكِيمٌۭ

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.
