إِنَّما يَعمُرُ مَساجِدَ اللَّهِ مَن آمَنَ بِاللَّهِ وَاليَومِ الآخِرِ وَأَقامَ الصَّلاةَ وَآتَى الزَّكاةَ وَلَم يَخشَ إِلَّا اللَّهَ ۖ فَعَسىٰ أُولـٰئِكَ أَن يَكونوا مِنَ المُهتَدينَ

The mosques of Allah are only to be maintained by those who believe in Allah and the Last Day and establish prayer and give zakah and do not fear except Allah, for it is expected that those will be of the [rightly] guided.
