{ Your women are a tilth for you, so approach your tilth whenever and however you wish; and put forth for yourselves } Al-baqara 223

{ Your women are a tilth for you } : that is, the place where you sow your child; { So approach your tilth } : that is, this place, the front part; { Whenever and however } : in what manner; { You wish } : standing up, sitting down, lying down, facing, or from behind. This came down in response to the Jews saying that whoever came to his woman in her front part from behind her, the child would be cross-eyed. { And put forth for yourselves } : acts of righteousness, such as tasmiyah [reciting Bismillah...] at the time of sex.
