Quran 42:49-50
"To Allah belongs the dominion of the heavens and the earth; He creates what he wills. He gives to whom He wills female [children], and He gives to whom He wills males. Or He makes them [both] males and females, and He renders whom He wills barren. Indeed, He is Knowing and Competent."
"Ufalme wa mbingu na ardhi ni wa Mwenyezi Mungu; anaumba apendavyo, anamtunukia amtakaye watoto wa kike, na anamtunukia amtakaye watoto wa kiume.
Au huwachanganya wanaume na wanawake, na akamfanya amtakaye tasa. Hakika Yeye ni Mjuzi Mwenye uweza"
