Musannaf Ibn Abi Shayba 3:4230

Hushaym narrated to us, he said: Yunus informed us, from al-Hasan, who said: The Messenger of Allah (may Allah bless him and grant him peace) said: "May Allah have mercy on a man who stood at night and prayed, then woke his family and they prayed. May Allah have mercy on a woman who stood at night and prayed, then woke her husband and he prayed."
