Sunan Abi Dawud Book 5, Hadith 59
The Prophet (ﷺ) said: May Allah have mercy on a man who gets up at night and prays, and awakens his wife; if she refuses, he should sprinkle water on her face. May Allah have mercy on a woman who gets up at night and prays, and awakens her husband; if he refuses, she would sprinkle water on his face.
Do not give up prayer at night, for the Messenger of Allah (ﷺ) would not leave it. Whenever he fell ill or lethargic, he would offer it sitting.
The Prophet (ﷺ) said: If a man awakens his wife at night, and then both pray or both offer two rak'ahs together, the (name of the )man will be recorded among those who mention the name of Allah, and the (name of the) woman will be recorded among those who mention the name of Allah. Ibn Kathir did not narrate this tradition as a statement of the Prophet (ﷺ), but he reported it as a statement of Abu Sa'id.
Abu Dawud said: This tradition has been narrated by Ibn Mahdi from Sufyan and I think he mentioned the name of Sufyan. He also said: The tradition transmitted by Sufyan is a statement of the Companion (and not that of the Prophet).
