Al-Insan 76:16–20

قَوَا۩رِيْرَا۟ مِنْ فِضَّةٍ (vessels of silver...76:16). Silver vessels in this world are dense which can never be like glass, and that which is made of glass can never be silver. Thus silver and glass are two contradictory concepts in this world. However, it is a characteristic of Paradise that its glasses will be as bright as silver, and as transparent and sparkling as crystal.

Sayyidna Ibn ` Abbas said: The blessings given in Paradise have their likes in this world also, except these vessels that are made of silver, but as transparent as a mirror."

وَيُسْقَوْنَ فِيْهَا كَاْسًا كَانَ مِزَاجُهَا زَنْجَبِيْلًا (And they will be served with a goblet of drink blended with ginger...76:17). The word zanjabil means 'ginger'. The Arabs loved that their drink should be mixed with ginger. Therefore, it is mentioned in the context of Paradise [ so that they are served with drinks flavoured with ginger of paradisiacal quality and splendour ]. Some scholars say that the only thing the blessings of Paradise and the blessings of this world share in common is their name, and they have nothing else in common. Therefore, the 'ginger' of this world cannot be equated with the 'ginger' of Paradise.
