Surat At-Tawbah - سورة التوبة

مَا كَانَ لِلْمُشْرِكِينَ أَن يَعْمُرُوا مَسَاجِدَ اللَّهِ شَاهِدِينَ عَلَىٰ أَنفُسِهِم بِالْكُفْرِ ۚ أُولَٰئِكَ حَبِطَتْ أَعْمَالُهُمْ وَفِي النَّارِ هُمْ خَالِدُونَ

Muhsin Khan: It is not for the Mushrikun (polytheists, idolaters, pagans, disbelievers in the Oneness of Allah), to maintain the Mosques of Allah (i.e. to pray and worship Allah therein, to look after their cleanliness and their building, etc.), while they witness against their ownselves of disbelief. The works of such are in vain and in Fire shall they abide.
