‘Abdallah b. ‘Amr b. al-‘As reported God’s Messenger as saying to him, “Don’t be like so and so, ‘Abdallah. He used to get up during the night, then abandoned the practice.”
Abu Huraira' reported God’s Messenger as saying, “God show mercy to a man who gets up during the night and prays, who wakens his wife and she prays, but if she refuses sprinkles the water on her face! God show mercy to a woman who gets up during the night and prays, who wakens her husband and he prays, but if he refuses sprinkles the water on his face!”
