Qur'an 9:18 · At-Tawba

إِنَّمَا يَعْمُرُ مَسَٰجِدَ ٱللَّهِ مَنْ ءَامَنَ بِٱللَّهِ وَٱلْيَوْمِ ٱلْءَاخِرِ وَأَقَامَ ٱلصَّلَوٰةَ وَءَاتَى ٱلزَّكَوٰةَ وَلَمْ يَخْشَ إِلَّا ٱللَّهَ ۖ فَعَسَىٰٓ أُو۟لَٰٓئِكَ أَن يَكُونُوا۟ مِنَ ٱلْمُهْتَدِينَ

(18) 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.
