The fals (Arabic: فلس, romanized: fals, plural fulus) was a medieval copper coin first produced by the Umayyad Caliphate (661–750) beginning in the late 7th century.
[1] As common with most Islamic coinage, the fals was aniconic and usually featured ornate Arabic script on both sides.
The term is still used in modern spoken Arabic for money, but pronounced 'fils'.
[2] The plural form fulus فلوس is used in contemporary dialects of Arabic (e.g. Egyptian, Iraqi) as a general term for "money".
It is also absorbed into Malay language through the word fulus فولوس.
