Allah says,
[وَيُطَافُ
عَلَيْهِمْ بِـَانِيَةٍ مِّن فِضَّةٍ وَأَكْوابٍ]
(And among them will be passed round vessels of silver and cups of crystal)
meaning, servants will go around them with containers of food made of silver and
cups of drink. These are drinking vessels that do not have handles or spouts.
Then Allah says,
[قَوَارِيرَاْقَوَارِيرَاْ مِن فِضَّةٍ]
((Qawarir) Crystal-clear, made of silver.) Ibn `Abbas, Mujahid, Al-Hasan
Al-Basri and others have all said, "It (Qawarir) is the whiteness of silver in
the transparency of glass.'' Qawarir is only made of glass. So these cups are
made of silver, but due to their fine thinness, what is inside of them will be
visible from outside of them (as if they are glass). This is among the things of
which there is nothing like in this world. Allah said,
[قَدَّرُوهَا
تَقْدِيراً]
(They will determine the measure thereof.) meaning, according to the amount
that will quench their thirst. It will not be more than that nor less than it,
rather it will be prepared in an amount that is suitable for quenching the
thirst of their drinkers. This is the meaning of the statement of Ibn `Abbas,
Mujahid, Sa`id bin Jubayr, Abu Salih, Qatadah, Ibn Abza, `Abdullah bin `Ubayd
bin `Umayr, Ash-Sha`bi and Ibn Zayd. This was stated by Ibn Jarir and others.
This is the most excellent provision, distinction and honor.
