17ما كانَ لِلمُشرِكينَ أَن يَعمُروا مَساجِدَ اللَّهِ شاهِدينَ عَلىٰ أَنفُسِهِم بِالكُفرِ ۚ أُولٰئِكَ حَبِطَت أَعمالُهُم وَفِي النّارِ هُم خالِدونَ(Irfan-ul-Quran)It is not for the polytheists to maintain and frequent the mosques of Allah whereas they themselves bear witness to their disbelief. All their deeds have become void and in Hell will they dwell forever.
