The Kitáb-i-Aqdas
Shoghi Effendi’s behalf it is explained that “the intercalary days are specially set aside for hospitality, the giving of gifts, etc.”.
30.The traveller ... not bound by the Fast ¶16
The minimum duration of a journey which exempts the believer from fasting is defined by Bahá’u’lláh (Q and A 22 and 75). The details of this provision are summarized in the Synopsis and Codification, section IV.B.5.a.i.-v.
Shoghi Effendi has clarified that while travellers are exempt from fasting, they are free to fast if they so wish. He also indicated that the exemption applies during the whole period of one’s travel, not just the hours one is in a train or car, etc.
31.The traveller, the ailing, those who are with child or giving suck, are not bound by the Fast; they have been exempted by God as a token of His grace. ¶16
Exemption from fasting is granted to those who are ill or of advanced age (see note 14), women in their courses (see note 20), travellers (see note 30) and to women who are pregnant and those who are nursing. This exemption is also extended to people who are engaged in heavy labour, who, at the same time, are advised “to show respect to the law of God and for the exalted station of the Fast” by eating “with frugality and in private” (Q and A 76). Shoghi Effendi has indicated that the types of work which would exempt people from the Fast will be defined by the Universal House of Justice.
32.Abstain from food and drink from sunrise to sundown ¶17
This relates to the period of fasting. In one of His Tablets, ‘Abdu’l-Bahá, after stating that fasting consists of abstinence from food and drink, further indicates that smoking is a form of “drink”. In Arabic the verb “drink” applies equally to smoking.
