A mosque is a place for prayer, worship, remembrance, and community religious life. Maintaining cleanliness, safety, lighting, and sound construction serves its purpose. Turning these efforts into a contest of public prestige can distort one's priorities.
Example 1: Two neighborhoods focus on access, cleanliness, and the experience of worshippers instead of competing for the grandest appearance.
Example 2: Appreciate a donor without turning their donation into an instrument of humiliation for others.
الْمَسَاجِدِ is the plural of مَسْجِد. It follows the preposition فِي, so it appears with a genitive ending.
