Though drinking alcohol is forbidden in Islam, in classical Persian literature wine was a common subject for most authors and poets. The debate as a popular genre was often used to let forbidden objects or ideas, in this case the wine, present the pro’s and con’s and argue about their position in an Islamic society. A very popular theme was the debate between wine and a rose. In this highly interesting article, the author discusses a treatise by the thirteenth century author Muhammad  Zangī Bukhārī Gul u mul (“The Rose and the Wine”).
The form of the debate offers the poet an opportunity to list both the positive and the negative qualities of each of the objects, using citations from even the Qur’an and prophetic traditions. He also must exploit all possible traits so that the speaking object can defend itself and prove its superiority to its adversary.
