يَا أَيُّهَا الَّذِينَ آمَنُوا إِنَّمَا الْمُشْرِكُونَ نَجَسٌ فَلَا يَقْرَبُوا الْمَسْجِدَ الْحَرَامَ بَعْدَ عَامِهِمْ هَـٰذَا ۚ وَإِنْ خِفْتُمْ عَيْلَةً فَسَوْفَ يُغْنِيكُمُ اللَّـهُ مِن فَضْلِهِ إِن شَاءَ ۚ إِنَّ اللَّـهَ عَلِيمٌ حَكِيمٌ[/size]
O you who have believed, indeed the polytheists are unclean, so let them not approach al-Masjid al-Haram after this, their [final] year. And if you fear privation, Allah will enrich you from His bounty if He wills. Indeed, Allah is Knowing and Wise.
Now what you'll never know unless you've been an ex-Muslim like me, is that the word نجس which is translated " unclean" is a specific technical term in Islam, meaning the the dirty things that no Muslim should ever physically touch or keep in sight.
The list of official Islamic "dirty" things are shit, piss, cum, dogs and pigs, and the atheist.
Not that i really care what some backward religion thinks of non believers. But your quote pertains to Polytheists and there appears to be no mention of Atheists!
