عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ: ((رَحِمَ اللَّهُ رَجُلًا قَامَ مِنَ اللَّيْلِ فَصَلَّى وَأَيْقَظَ امْرَأَتَهُ فَصَلَّتْ، فَإِنْ أَبَتْ نَضَحَ فِي وَجْهِهَا الْمَاءَ، وَرَحِمَ اللَّهَ امْرَأَةً قَامَتْ مِنَ اللَّيْلِ فَصَلَّتْ وَأَيْقَظَتْ زَوْجَهَا فَصَلَّى، فَإِنْ أَبَى نَضَحَتْ فِي وَجْهِهِ الْمَاءِ))
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 stands at night and prays, and awakens his wife, and she also prays. If she refuses to get up, he sprinkles water on her face. And likewise, may Allah have mercy on the woman who gets up at night and prays, and awakens her husband, and he also prays. If he refuses to get up, she sprinkles water on his face.
