At Tawbah Ayah 28

يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓاْ إِنَّمَا ٱلْمُشْرِكُونَ نَجَسٌ فَلَا يَقْرَبُواْ ٱلْمَسْجِدَ ٱلْحَرَامَ بَعْدَ عَامِهِمْ هَـٰذَا‌ۚ وَإِنْ خِفْتُمْ عَيْلَةً فَسَوْفَ يُغْنِيكُمُ ٱللَّهُ مِن فَضْلِهِۦٓ إِن شَآءَ‌ۚ إِنَّ ٱللَّهَ عَلِيمٌ حَكِيمٌ ٢٨ O believers! Indeed, the polytheists are ?spiritually? impure, so they should not approach the Sacred Mosque after this year. If you fear poverty, Allah will enrich you out of His bounty, if He wills. Surely, Allah is All-Knowing, All-Wise.
