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

The mosques of God are tended only by those who believe in God and the last day, who establish prayer, give the purifying alms, and fear none but God. It is they who may hope to be among the rightly guided.
Yaʿmuru covers two kinds of care, keeping a building standing and filling it with people at worship, and ʿumra, the visit to the Kaaba, grows from the same letters. Commentators have kept both senses in play here. After every condition is met, the verse still closes on ʿasā, they may hope, and Ibn ʿAbbas is reported to have said that each ʿasā spoken by God is a certainty, which leaves the uncertainty on the human side of the sentence.
