Tafsir of Al-Furqan 25:54

وهو الذي خلق من الماء بشرا

And it is He Who has created man from water, means, He created man from a weak Nutfah, then gave him shape and formed him, and completed his form, male and female, as He willed.

فجعله نسبا وصهرا

and has appointed for him kindred by blood, and kindred by marriage. in the beginning, he is someone's child, then he gets married and becomes a son-in-law, then he himself has sons-in-law and other relatives through marriage. All of this comes from a despised liquid, Allah says:

وكان ربك قديرا

And your Lord is Ever All-Powerful to do what He wills
