"Permitted to you, on the night of the fasts, is the approach to your wives. They are your garments and ye are their garments. Allah knoweth what ye used to do secretly among yourselves; but He turned to you and forgave you; so now associate with them, and seek what Allah Hath ordained for you, and eat and drink, until the white thread of dawn appear to you distinct from its black thread; then complete your fast Till the night appears; but do not associate with your wives while ye are in retreat in the mosques.

This is based on the messenger of Allah (peace be upon him) marrying Aisha without her consent when she was less than nine years old, as is stated in authentic Hadith." - Shaikh ibn Baz
