Thanks for your post.. Sorry I overlooked the thread until now but I'd be happy to respond to your post.
I'm not speaking for Islam.. but only as a Baha'i.
The Kitab-i-Aqdas which Baha'u'llah revealed around 1871 in Akka is the book that has the laws and ordinances of the Baha'i Faith.
An authorized version in English was available in 1992.
It is not a large book as books go consisting of seventy two pages. So the ordinances of our Faith is contained in a very small book compared to say the books of canon law in traditional Christianity or say the Buddhist Monastic Code, the Laws of Manu, the Sharia codes, Halakha and so on..
Not all the ordinances of the Kitab-i-Aqdas are operable..that is, they have yet to be instituted as yet as they are meant for a future time for larger Baha'i communities.
The "Golden Rule":
"So whatever you wish that men would do to you, do so to them; for this is the Law and the prophets."
(Matthew 7:12 RSV)
goes a bit further in the Baha'i Writings:
"Blessed is he who preferreth his brother
before himself."
It seems Yardstick that you have a concern about the Baha'i law to abstain from alcohol.. Baha'is do not drink alcohol.. We can use it as a solvent or cleanser.. If it's prescribed by a doctor it can be used as a medicine, but other wise it is forbidden for us.
There are cases in the Bible where people abstained from wine:
6:1 And the LORD spake unto Moses, saying, 6:2 Speak unto the children of Israel, and say unto them, When either man or woman shall separate themselves to vow a vow of a Nazarite, to separate themselves unto the LORD: 6:3
He shall separate himself from wine and strong drink, and shall drink no vinegar of wine, or vinegar of strong drink, neither shall he drink any liquor of grapes, nor eat moist grapes, or dried.
(King James Bible, Numbers)
Also many Christians abstain from alcoholic beverages..ever heard of the Temperance movement? My grandmother a Methodist was a prohibitionist.
