March 9

The Universal House of Justice has received your letter of 7 March 1991 concerning exemption from fasting and obligatory prayers in the case of an individual suffering from alcoholism. We have been asked to convey the following. 

Regarding the Fast, as you know, there is exemption for those who are ill. The answer to your question, therefore, should be determined on the basis of competent medical advice. Ultimately, the keeping of the Fast and saying of the obligatory prayers are left to the conscience of the individual.
