Masjid Kuala Dulang (GPS: 2.93223, 102.08005) is the oldest mosque in Jelebu, Negeri Sembilan. Located in the village of Kuala Dulang, to the southeast of the district administrative centre of Kuala Klawang, the mosque was founded in the 16th century by two Muslim missionaries, Dato Nika and Mudim Khatib Raja. They also founded the village of Kampung Peninjau.
In the beginning, the mosque was just a shed with thatch roofing. It was where the Muslim missionaries had sought shelter. It is said that a tray, or dulang, filled with food had mysteriously appeared, and would continue to be filled with food no matter how often worshippers ate from it. The tray disappeared a few years after, as mysteriously as how it had first appeared.
