Jabir (Allah be pleased with him) declared that the Jews used to say
When a man has intercourse with his wife through the vagina but being on her back. the child will have squint, so the verse came down:" Your wives are your tilth; go then unto your tilth as you may desire" (ii. 223)
Jabir (b. Abdullah) (Allah be pleased with him) reported that the Jews used to say that when one comes to one's wife through the vagina, but being on her back, and she becomes pregnant, the child has a squint. So the verse came down
" Your wives are your ti'Ith; go then unto your tilth, as you may desire."
This hadith has been reported on the authority of Jabir through another chain of transmitters, but in the hadith transmitted on the authority of Zuhri there is an addition (of these words)
" If he likes he may (have intercourse) being on the back or in front of her, but it should be through one opening (vagina)."
