Inside a mosque, a man in black clothes and barefoot fills a bottle at a water dispenser

Inside a mosque, a man in black clothes and barefoot fills a bottle at a water dispenser. Other people are praying in the background, some visible through a wooden-framed window or doorway. Signs on the wall near the water dispenser in Indonesian indicate "Area Diawasi CCTV" and emphasize the importance of cleanliness in the mosque area. The tiled floor is grey and patterned.
