Quran 9:18 At-Tawbah, ayah 18 of 129

إِنَّمَا يَعْمُرُ مَسَـٰجِدَ ٱللَّهِ مَنْ ءَامَنَ بِٱللَّهِ وَٱلْيَوْمِ ٱلْـَٔاخِرِ وَأَقَامَ ٱلصَّلَوٰةَ وَءَاتَى ٱلزَّكَوٰةَ وَلَمْ يَخْشَ إِلَّا ٱللَّهَ ۖ فَعَسَىٰٓ أُو۟لَـٰٓئِكَ أَن يَكُونُوا۟ مِنَ ٱلْمُهْتَدِينَ ۝١٨

9:18 He only shall tend Allah's sanctuaries who believeth in Allah and the Last Day and observeth proper worship and payeth the poor-due and feareth none save Allah. For such (only) is it possible that they can be of the rightly guided.
