And He is the One Who merges the two bodies of water: one fresh and palatable and the other salty and bitter, placing between them a barrier they cannot cross.1
And He is the One Who creates human beings from a ˹humble˺ liquid,1 then establishes for them bonds of kinship and marriage. For your Lord is Most Capable.
