Euphrates

If a person sees himself drink water from the Euphrates river in a dream, it signifies benefit and blessing that will be bestowed by Allah Most High.

Seeing the Euphrates river dry up is a sign of the death of the head of state. Or it signifies that his dominion will slip from his hands and that he will perish. Again, seeing oneself drink the water of the Euphrates is interpreted as praying much and worshipping. This dream is also a sign of that person's contentment.
