In Paradise there are many springs that provide drinks of different tastes:

“Truly al-Muttaqoon [the pious and righteous] will be amidst Gardens and Water-springs” [15:45]

“Verily al-Muttaqoon shall be amidst shades and springs.” [77:41]

Concerning the two Gardens which Allah (swt) has prepared for those who fear their Rabb, Allah (swt) said, “In them [both] will be two springs flowing [free].” [55:50]

And concerning the two Gardens beneath them, He said, “In them [both] will be two springs gushing forth water.” [55:66]

In Paradise there are two springs from which al-Muqarraboon will drink pure and undiluted, whilst the Abraar will drink their water mixed with something else. The first is the spring of Kafoor, as Allah (swt) says:

“Verily the Abraar [the pious, those who fear Allah and avoid evil], shall drink a cup [of wine] mixed with water from a spring in Paradise called Kafoor, A spring where from the slaves of Allah will drink, causing it to gush forth abundantly.” [76:5-6]

He tells us that the pious will drink from it mixed with something else, whilst those close to Allah will drink it pure and undiluted.

The second spring is of Tasneem, as Allah (swt) says:

“Verily al-Abraar will be in delight [Paradise], On thrones, looking [at all things]. You will recognize in their faces the brightness of delight. They will b given to drink pure sealed wine, the last thereof [that wine] will be the smell of musk, and for this let [all] those who strive who want to strive [ i.e. hasten earnestly to the obedience of Allah]. It [that wine] will be mixed with Tasneem, a spring whereof drink those nearest to Allah.” [83:22-27]

Another of the springs of Paradise is called al-Salsabeel as Allah (swt) says:

“And they will be given to drink there a cup [of wine] mixed with zanjabeel [ginger], a spring there, called Salsabeel”. [76:17-18]

This is probably the same spring as that mentioned above, i.e. Kafoor.
