Rambam says "ושמע האמת ממי שאמרה" ("Accept the truth from whomever says it") in Shmonah Perakim. Does anyone know what he said in the original Judeo Arabic?
It is ואסמע אלחק ממן קאלה.
You can read the Judeo-Arabic original (in Hebrew letters, as it was written) here.
Arabic lettering for reference:
واسمع الحق ممن قاله
wasmae alhaqa mmn qalaha
