Qur'an 9:28

يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓا۟ إِنَّمَا ٱلْمُشْرِكُونَ نَجَسٌ فَلَا يَقْرَبُوا۟ ٱلْمَسْجِدَ ٱلْحَرَامَ بَعْدَ عَامِهِمْ هَـٰذَا ۚ وَإِنْ خِفْتُمْ عَيْلَةً فَسَوْفَ يُغْنِيكُمُ ٱللَّهُ مِن فَضْلِهِۦٓ إِن شَآءَ ۚ إِنَّ ٱللَّهَ عَلِيمٌ حَكِيمٌ

“O you who have believed, indeed the polytheists are unclean, so let them not approach al-Masjid al-Ḥarām after this, their [final] year. And if you fear privation, Allāh will enrich you from His bounty if He wills. Indeed, Allāh is Knowing and Wise.”
