Surah At-Taubah (The Repentance), Verse 18

اِنَّمَا یَعْمُرُ مَسٰجِدَ اللّٰهِ مَنْ اٰمَنَ بِاللّٰهِ وَالْیَوْمِ الْاٰخِرِ وَاَقَامَ الصَّلٰوةَ وَاٰتَی الزَّكٰوةَ وَلَمْ یَخْشَ اِلَّا اللّٰهَ فَعَسٰۤی اُولٰٓىِٕكَ اَنْ یَّكُوْنُوْا مِنَ الْمُهْتَدِیْنَ ۟

“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.”
