صباح الخير - صباح النور؟!

In his 'Dictionary Of Prohibited Terms' (p. 334), Al-'Allāmāh Bakr Abū Zaid raḥimahullāh wrote: "There is an interesting article in 'The Journal Of The Arabic Language Academy in Egypt' written by Professor 'Umar Farrūkh, in which he stated: "Most people, when they greet each other, say: صباح الخير أو مساء الخير! 'Good morning' or 'Good evening!' And the response to this greeting is: صباح النور - مساء النور! 'Morning of Light' - 'Evening of Light' This greeting is the Zoroastrian greeting. The Zoroastrian believe in two forces: good and evil, represented by light and darkness. The Zoroastrians have a God of good or light and a God of evil or darkness, and they (these two Gods) vie for control over the world. Thus, it made sense for the Zoroastrians to greet each other with: صباح الخير - صباح النور! 'Good Morning' - 'Morning of Light!' Even though Islam has commanded us to use the Islamic greeting: السلام عليكم - 'Peace be upon you' in place of any other greeting. Arabs, for the most part, whether Muslim or non-Muslim, still exchange greetings by saying: صباح الخير - صباح النور! 'Good Morning' - 'Morning of Light'." [End quote] @mufradaatun
