Surah At-Tawbah, Verse 18

إِنَّمَا يَعۡمُرُ مَسَٰجِدَ ٱللَّهِ مَنۡ ءَامَنَ بِٱللَّهِ وَٱلۡيَوۡمِ ٱلۡأٓخِرِ وَأَقَامَ ٱلصَّلَوٰةَ وَءَاتَى ٱلزَّكَوٰةَ وَلَمۡ يَخۡشَ إِلَّا ٱللَّهَۖ فَعَسَىٰٓ أُوْلَٰٓئِكَ أَن يَكُونُواْ مِنَ ٱلۡمُهۡتَدِينَ١٨

innamā yaʿmuru masājida l-lahi man āmana bil-lahi wal-yawmi l-ākhiri wa-aqāma l-ṣalata waātā l-zakata walam yakhsha illā l-laha faʿasā ulāika an yakūnū mina l-muh'tadīna

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.
