Sura al-Tawbah 9:18

إِنَّمَا يَعْمُرُ مَسَٰجِدَ ٱللَّـهِ مَنْ ءَامَنَ بِٱللَّـهِ وَٱلْيَوْمِ ٱلْأَخِرِ وَأَقَامَ ٱلصَّلَوٰةَ وَءَاتَى ٱلزَّكَوٰةَ وَلَمْ يَخْشَ إِلَّا ٱللَّـهَ فَعَسَىٰٓ أُو۟لَٰٓئِكَ أَن يَكُونُوا۟ مِنَ ٱلْمُهْتَدِينَ

innamā yaʿmuru masājida allāhi man āmana billāhi wa-l-yawmi l-akhiri wa-aqāma l-ṣalāta wa-ātā l-zakāta wa-lam yakhshā illā allāha fa-ʿaṣā ulāʾika an yakūnū mina l-muhtadīna

The mosques of Allah shall be visited and maintained by such as believe in Allah and the Last Day, establish regular prayers, and practise regular charity, and fear none (at all) except Allah. It is they who are expected to be on true guidance.
