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. -- Qur'an 42:49-50
These ayat came up in my previous question Does the Qur'an 75:39 ("He made of him a pair, male and female?") exclude the possibility of people who are neither male nor female?
Question: Should "Or He makes them [both] males and females" be interpreted as referring to intersex people?
It seems plausible that this instead refers to instances of male-female twins.
