It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: May Allah have mercy on the man who gets up at night and prays, and then wakes up his wife and she also prays, and if she refuses, he sprinkles water on her face. Likewise, may Allah have mercy on the woman who gets up at night and prays, and then wakes up her husband and he also prays, and if he refuses, she sprinkles water on his face to wake him up.
