unmixed by those brought near to Allah, while it is mixed for the companions of the right.”

Allah Most High says:

“They will be given a cup to drink there, mixed with ginger,
From a spring there called Salsabīl.”

Allah Most High also says:

“Then the companions of the right—what are the companions of the right!
And the companions of the left—what are the companions of the left!
And the foremost—the foremost!
They are those brought near to Allah.”

Allah Most High also says:

“If he is one of those brought near to Allah,
Then there will be rest, sweet fragrance, and a Garden of bliss.
And if he is one of the companions of the right,
Then, ‘Peace be upon you,’ from the companions of the right.”
