Wrong.
Manila derived its name from two Tagalog words; "may," meaning "there is," and "nilad," the name of a shrub that originally grew abundantly along the shores of the Pasig River and Manila Bay.
Manila - A History
Okay, no need to put "wrong" into that bold......
Manila history also has "Islam color" on it, similar like Spain who was under Islamic Kingdom for 7 Centuries (Umayyah)
----------------------------------------------------------------------------------------------------
The former city of Manila was once a province of the
Majapahit Empire. During the
Brunei invasion of the Philippines,
Sultan Bolkiah of Brunei captured
Seludong (a village in modern-day Manila) and renamed it Maynilà
[11] from the word "Maynilad", a Tagalog term referring to the presence of the
Nila shrub.
By the 15th century, Maynilà was partly Islamic and animist.
During the reign of Sultan
Bolkiah from 1485 to 1521, the
Bruneian Empire invaded, wanting to take advantage of
Tondo's China trade by attacking its environs and establishing "كوتا سلودوڠ Kota Saludong" (The
Kingdom of Maynila). They ruled under and gave yearly tribute to the Sultanate of
Brunei as its
satellite state.
[11] They established a new dynasty under the local leader who accepted Islam and became Rajah Salalila or Tariq Sulayman I. He also established a trading challenge to the already rich House of
Lakan Dula in
Tondo.
Islam was further strengthened by the arrival of Muslim traders from the Arab-Indian area and Southeast Asia.
[18] Manila was temporarily besieged by the invasion of Chinese pirate-warlord
Limahong (1574) before it became the seat of the
colonial government of
Spain.
