It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: May Allah bestow His mercy upon the person who gets up at night and prays, and also wakes up his wife to pray; and if she refuses, he sprinkles water on her face. And may Allah's mercy descend upon the woman who gets up at night and prays, and wakes up her husband to pray; and if he refuses, she sprinkles water on his face.
