Musannaf Ibn Abi Shayba 9:117

Abu Bakr narrated to us, he said: Hushaym narrated to us, from ‘Awf, from Anas, who said: When he would marry off a woman from his daughters or a woman from some of his family members, he would say to her husband: "I marry you [to her] upon holding [her] with kindness or releasing [her] with goodness."
