Qanun
Laws and regulations enacted by a government. Qanun were meant to be supplements to Islamic law in matters it left insufficiently regulated. Under the Ottoman sultans, qanun became an integral part of the legal system, especially in the administrative, fiscal, and penal domains. The sultan's prerogative to enforce customary practices deemed publicly beneficial was a main justification of qanun. In the modern era, qanun gradually became a generic name for all laws and regulations. Similar developments took place in other Muslim countries under such different names as dustur and nizam.

QANUN
Qanun (pl. qawanin) is a word that apparently entered into Arabic from Greek, although according to some reports it might have been borrowed from Persian or Latin or have meant the "way to something" or its measurement in old Arabic. The word, however, has come to have broad meanings including a particular musical instrument, known simply as al-qanun, tax assessments, state taxes and tariffs, registers and lists, land measurements, and also rules and regulations. In modern times, qanun generally refers to state law, although the word is often used to signify guiding rules, customs, and principles. In both premodern and modern times, qanun often referred to secular laws and administrative rules, as opposed to religious laws or shari˓a.
