The Sheikh Karimul Makhdum Mosque is located in Barangay Tubig Indangan, Simunul, Tawi-Tawi, the Philippines.

[2] According to local folklore, it was built by a Syrian Arab trader and Sunni Sufi scholar named Sheikh Karimul Makhdum in 1380.

[3] However, studies from the National Museum of the Philippines have confirmed that the pillars found within the present mosque dates back to the 17th century.

[4] The four pillars are regarded as sacred and have high status in Philippine culture as they are at least 400 years old and are the oldest known Islamic artifacts in the entire Philippines.

[5] The current mosque building was constructed in the 1960s, after most of the prior structure was burned down in 1941 during the Japanese occupation of World War II.
