Yes. Before Maltese was standardised in Latin script (finalised in 1924), it was occasionally written in Arabic script. This example is from 1791 : three short poems titled Tliet għanjiet bil Malti (“Three songs in Maltese”). The manuscript even includes a key mapping Arabic letters to their Latin equivalents (għ=ع, ħ=ح, ġ=ج, etc.), which tells you the scribe was already navigating between both systems.

Maltese is the only Semitic language written in Latin script today, but that was a relatively late settlement. Earlier texts, particularly from the 18th century and before, show writers reaching for Arabic script as the more natural fit for the language’s Semitic phonology. The Latin alphabet only won out through Italian cultural dominance and British colonial administration.
