Mishkat al-Masabih #3012

Abu Sa'id and Ibn ‘Abbas reported God’s Messenger as saying, “He who has a son born to him should give him a good name and a good education and marry him when he reaches puberty. If he does not marry him when he reaches puberty and He commits sin, its guilt rests only upon his father." Baihaqi transmitted in Shu'ab al-iman.
