﴿ عَيْنًۭا يَشْرَبُ بِهَا عِبَادُ ٱللَّهِ يُفَجِّرُونَهَا تَفْجِيرًۭا ﴾

“a source [of bliss] whereof God's servants shall drink, seeing it flow in a flow abundant.”

a spring ‘aynan substitutes for kāfūran containing the scent thereof from which the servants of God His friends drink making it gush forth plenteously directing it to wherever they wish of their dwellings.
