This is because Maguindanao language doesn't have its own specific word for "friend" or "how are you". It uses the same words as Tagalog.
However, the pronunciation may differ slightly depending on the specific dialect.
Here's a more informal and casual way to say "How are you, friend?" in Maguindanao:
* "A-piya ka?" (Informal greeting, meaning "How are you?") + "Kaibigan" (Friend)
* "A-piya ka, kaibigan?" (Combined informal greeting and "friend")
Remember, "Kumusta ka kaibigan" is perfectly understandable and commonly used in Maguindanao.
