Engineering:Salsabil
Salsabil (Arabic: سلسبيل Salsabīl) is an Arabic term, borrowed into many languages, with a variety of meanings. Salsabil can also be written as "salsabiil", "salasabil", or even "salsabeel", but "salsabil" is the most common spelling.[citation needed]
In the Quran
In the Quran, the word is used once to refer to a spring in paradise (Jannah). It can also mean river or fountain in paradise.[clarification needed] The sole quranic reference is in sura Al-Insan.
"And there they will be given a cup whose mixture is of Zanjabil (ginger). A fountain there, called Salsabil."— Quran, sura 76 (Al-Insan), ayat 17-18[1]
The verse may be in reference to the previous verse concerning the drink provided to those who enter paradise.

The word is used in Hindustani to mean "[r]unning limpid, sweet water".[2][better source needed]
It is also used to refer to a type of fountain used for evaporative cooling. The water flows in a thin sheet, often over a wavy surface with many little waterfalls, in a manner designed to maximize the surface area and thus evaporation. It may be a near-vertical marble waterfall mounted on a wall[3] or the sheet of water may flow down a slanted chute.[4]
Passive ventilation may be used to maximize the flow of unsaturated air over the water surface and carry the cooled air to where it is needed in the building. Salasabils are often used with windcatchers.[5]
Use extends from southern Spain to northern India . Salasabils were used in Moghul architecture from the 1200s to the 1600s. They were also used in recent centuries in Iran.[4]
A salasabil may also be used to aerate water for drinking in a sebil.[6]:63, 262
