سورة التوبة

إِنَّمَا يَعْمُرُ مَسَاجِدَ اللَّهِ مَنْ آمَنَ بِاللَّهِ وَالْيَوْمِ الْآخِرِ وَأَقَامَ الصَّلَاةَ وَآتَى الزَّكَاةَ وَلَمْ يَخْشَ إِلَّا اللَّهَ ۖ فَعَسَىٰ أُولَٰئِكَ أَنْ يَكُونُوا مِنَ الْمُهْتَدِينَ ﴿١٨﴾

Surah at-Tawbah

18. The only people to attend Allah’s mosques are those who believe in Allah and the Last Day, and pray regularly, and practice regular charity, and fear none except Allah. These are most likely to be guided.
