Allah Subhanahu wa Ta'ala says (Translation): Verily the righteous shall drink from a (cup of wine) flavoured with Camphor from a spring of Paradise called Kafur. A spring from where the slaves of Allah will drink, causing it to gush forth (wherever they wish) abundantly. They (are those) who fulfil their ordained deeds sincerely, and they fear a Day whose evil will be wide spread (to one and all). And they feed, for the love for Him, the poor, the orphans, and the captives, (Saying:) We feed you, seeking only Allah's countenance. We wish from you no reward, nor thanks. Verily we fear from our Sustainer a Day, hard and distressful. So, Allah will save them from the evil of that Day (for their obedience and sincerity) and give them a light of beauty and joy. And their recompense shall be Paradise and silken attire. They will be reclining therein on raised couches; they will find therein neither (the heat of) a sun nor the bitter cold. 'And the shade of the trees is close upon them; and the branches of fruits thereof will hang low within their reach. And amongst them will be passed around goblets of silver and beakers (as) of glass, Crystal clear, but made of silver. They will determine the measure thereof, according to their desire. And they will be given to drink from a cup (of wine) mixed with Zanjabil (ginger flavoured), From a spring called Salsabil. And youths of everlasting youth will serve them; when you look at them you would think they were as scattered pearls; And when you look there (in Paradise), you will see a delight (that cannot be imagined) and a great dominion. Their raiment will be of fine green silk, and gold embroidery. They will be adorned with bracelets of silver; and their Sustainer will slake their thirst by giving them a pure drink Himself. (And it will be said to them): Verily, this is a reward for you; and your endeavour has found acceptance. (Al-Insan 76: 5-22)
