17ما كانَ لِلمُشرِكينَ أَن يَعمُروا مَساجِدَ اللَّهِ شاهِدينَ عَلىٰ أَنفُسِهِم بِالكُفرِ ۚ أُولٰئِكَ حَبِطَت أَعمالُهُم وَفِي النّارِ هُم خالِدونَZafar AnsariIt does not become those who associate others with Allah in His Divinity to visit and tend Allah's mosques while they bear witness of unbelief against themselves. All their works have gone to waste. They shall abide in the Fire.
