باب التَّعَاوُنِ فِي بِنَاءِ الْمَسْجِدِ
"It is not for 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), while they witness against their ownselves of disbelief. The works of such are in vain, and in Fire shall they abide.
The Mosques of Allah shall be maintained only by those who believe in Allah and the Last Day, perform Salat (Iqamat-as-Salat) and give Zakat and fear none but Allah. It is they who are on true guidance." (V.9:17,18).
{مَا كَانَ لِلْمُشْرِكِينَ أَنْ يَعْمُرُوا مَسَاجِدَ اللَّهِ شَاهِدِينَ عَلَى أَنْفُسِهِمْ بِالْكُفْرِ أُولَئِكَ حَبِطَتْ أَعْمَالُهُمْ وَفِي النَّارِ هُمْ خَالِدُونَ إِنَّمَا يَعْمُرُ مَسَاجِدَ اللَّهِ مَنْ آمَنَ بِاللَّهِ وَالْيَوْمِ الآخِرِ وَأَقَامَ الصَّلاَةَ وَآتَى الزَّكَاةَ وَلَمْ يَخْشَ إِلاَّ اللَّهَ فَعَسَى أُولَئِكَ أَنْ يَكُونُوا مِنَ الْمُهْتَدِينَ}.
