AAaynan yashrabu biha AAibadu Allahi yufajjiroonaha tafjeera (surah Insan: 6)

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(76:6) This will be a gushing spring *7 wherefrom Allah's servants *8 shall drink wine, a spring from which they will take out channels wherever they wish. *9

Aynany yashrabu bihaa `ibaadul laahi yafajjiroonahaa tafjeeraa

*7) That is, it will not be camphor-mixed water but a natural fountain, the purity, coolness and agreeable odour of whose water will resemble camphor.
*8) Although the words 'ibad Allah (servants of Allah), or `ibad ar-Rehman (servants of Rehman), can be used for all then literally, for every human being is God's servant, yet wherever these words occur in the Qur'an they only imply the righteous men. In other words, the wicked ones who have excused themselves from Allah's servitude do not deserve that AIIah should honour them with the honourable title of ibad-Allah or ibad ar-Rehman, attributing them to His own Holy Name.
*9) It does not mean that they will use spades and showels to dig out its channels and will take out its branches whithersoever they please, but that their one single command and desire will be enough to cause a fountain to gush forth from wherever they please in Paradise.
