Quran At-Tawbah 9:18
إِنَّمَا يَعۡمُرُ مَسَٰجِدَ ٱللَّهِ مَنۡ ءَامَنَ بِٱللَّهِ وَٱلۡيَوۡمِ ٱلۡأٓخِرِ وَأَقَامَ ٱلصَّلَوٰةَ وَءَاتَى ٱلزَّكَوٰةَ وَلَمۡ يَخۡشَ إِلَّا ٱللَّهَۖ فَعَسَىٰٓ أُوْلَٰٓئِكَ أَن يَكُونُواْ مِنَ ٱلۡمُهۡتَدِينَ ١٨
Translation
The mosques of Allāh are only to be maintained by those who believe in Allāh and the Last Day and establish prayer and give zakāh and do not fear except Allāh, for it is expected that those will be of the [rightly] guided.
