The river in Jannah is known as Al-Kawthar, which translates to "Abundance" or "The Best."
It is a river of pure water, described in the Quran as being sweeter than honey and cooler than snow.
According to Islamic tradition, the river flows through Jannah (Paradise) and is a source of immense pleasure and refreshment for the inhabitants.
The river is also believed to have miraculous properties, such as healing the sick and cleansing the soul.
Those who drink from the river will never thirst again.
The river is a symbol of God's infinite mercy and blessings bestowed upon the righteous.
