Surah 83. Al-Mutaffifin
Ayah 18 - 28
18 كَلَّآ إِنَّ كِتَـٰبَ ٱلْأَبْرَارِ لَفِى عِلِّيِّينَ
19 وَمَآ أَدْرَىٰكَ مَا عِلِّيُّونَ
20 كِتَـٰبٌ مَّرْقُومٌ
21 يَشْهَدُهُ ٱلْمُقَرَّبُونَ
22 إِنَّ ٱلْأَبْرَارَ لَفِى نَعِيمٍ
23 عَلَى ٱلْأَرَآئِكِ يَنظُرُونَ
24 تَعْرِفُ فِى وُجُوهِهِمْ نَضْرَةَ ٱلنَّعِيمِ
25 يُسْقَوْنَ مِن رَّحِيقٍ مَّخْتُومٍ
26 خِتَـٰمُهُۥ مِسْكٌ ۚ وَفِى ذَٰلِكَ فَلْيَتَنَافَسِ ٱلْمُتَنَـٰفِسُونَ
27 وَمِزَاجُهُۥ مِن تَسْنِيمٍ
28 عَيْنًا يَشْرَبُ بِهَا ٱلْمُقَرَّبُونَ
[18-28] Indeed not!9 Surely the record of the righteous is in the Register of the exalted ones. And do you know what is the Register of the exalted ones? It is a written book, guarded by the angels nearest to Allah. Surely the righteous shall be in bliss; seated on high couches they shall be looking around. In their faces you shall mark the glow of bliss. They shall be given to drink the choicest, sealed wine whose seal shall be musk.10 Those who wish to excel others, let them endeavor to excel in this. That wine shall have the mixture of Tasnim.11 This is a fountain with the waters of which those nearest to Allah shall drink wine.
9That is, they are wrong in thinking that there is going to be no meting out of rewards and punishments.
10One meaning of the words khltamu-hu misk is that the vessels containing the wine will carry the seal of musk instead of clay or wax. Accordingly the verse means: This will be the choicest kind of wine, which will be superior to the wine flowing in the canals, and it will be served by the attendants of Paradise in vessels sealed with musk to the dwellers of Paradise. Another meaning also can be: When that wine will pass down the throat, its final effect will be of the flavor of musk. This state is contrary to the wines of the world which give out an offensive smell as soon as the bottle opens and one feels its horrid smell even while drinking and also when it passes down the throat.
11"Tasnim ".: height. Thus, Tasnim will be a fountain flowing down from a height.
