it does not cause their heads to ache or their minds to be fogged; it is pure, although it still contains the ingredients that make it a delight to the drinker. Ad-Dahhâk narrated that Ibn 'Abbâs said, "Wine produces four things: drunkenness, headache, vomit and urine. Allâh (saw) has mentioned the wine of Paradise, and He has purified it of all these things." [Tafsîr Ibn Kathîr, 6/514]
