Fear ye God, O people of the earth, and think not that the wine We have mentioned in Our Tablet is the wine which men drink, and which causeth their intelligence to pass away, their human nature to be perverted, their light to be changed, and their purity to be soiled.

Bahá’u’lláh, The Compilation of Compilations vol II, p. 245

Make thy home in taverns, but tread not the path of the mischief-maker.

Bahá’u’lláh, The Compilation of Compilations vol II, p. 337

According to the text of the Book of Aqdas, both light and strong drinks are prohibited. The reason for this prohibition is that alcohol leadeth the mind astray and causeth the weakening of the body. If alcohol were beneficial, it would have been brought into the world by the Divine creation and not by the effort of man. Whatever is beneficial for man existeth in creation. Now it hath been proved and is established medically and scientifically that liquor is harmful.

"As to the meaning of that which is written in the Tablets: 'I have chosen for thee whatsoever is in the heaven and the earth', this signifieth those things which are in accordance with the Divine purpose and not the things which are harmful. For instance, one of the existing things is poison. Can we say that poison must be used as it hath been created by God? Nevertheless, intoxicating liquor, if prescribed by a physician for the patient and if its use is absolutely necessary, then it is permissible.

"In brief, I hope that thou mayest become inebriated with the wine of the love of God, find eternal bliss and receive inexhaustible joy and happiness.

‘Abdu’l-Bahá, Lights of Guidance, p. 349

All wine hath depression as an after effect, except the wine of the Love of God.

‘Abdu’l-Bahá, Lights of Guidance, p. 349

As a safeguard against intemperance he does not drink wine or spirits. Bahá’u’lláh has said it is not good for a sane man to take that which will destroy his health and sense.

‘Abdu’l-Bahá, ‘Abdu’l-Bahá in London, p. 56

O ye, God's loved ones! Experience hath shown how greatly the renouncing of . . . intoxicating drink . . . conduceth to health and vigour, to the expansion and keenness of the mind and to bodily strength. There is today a people [possibly ‘Abdu’l-Bahá was referring to the Sikhs; the description appears to apply to them] who strictly avoid tobacco, intoxicating liquor and opium. This people is far and away superior to the others, for strength and physical courage, for health, beauty and comeliness. A single one of their men can stand up to ten men of another tribe. This hath proved true of the entire people: that is, member for member, each individual of this community is in every respect superior to the individuals of other communities.
