Drinking non-alcoholic wine in wine cups cannot be regarded as
prohibited as far as the Sharī‘ah is concerned. One must know that what has
been forbidden is alcohol. The cups or glasses in which it is generally
drunk do not bear any label of prohibition if they are properly cleaned and
used for non-alcoholic drinks.
Of course, a Muslim might find it to be against his taste and disposition to
drink from such glasses, but then this is a matter of personal choice and
cannot be generalized for all occasions and for all peoples.
