Narrated Jabir:

Jews used to say: "If one has sexual intercourse with his wife from the back, then she will deliver a 
squint-eyed child." So this Verse was revealed:-- 
"Your wives are a tilth unto you; so go to your tilth when or how you will." (2.223)

"Your wives are a tilth for you; so go to your tilth (have sexual relations with your wives in any manner as long as it is in the vagina and not in the anus) when or how you will..." (V.2:223)
