Abu Hurairah reports that the Prophet said: “May Allah bless the man who gets up during the night to pray and wakes up his wife and who, if she refuses to get up, sprinkles water on her face. And may Allah bless the woman who gets up during the night to pray and wakes up her husband and who, if he refuses sprinkles water on his face.” The Prophet sallallahu alehi wasallam also said: “If a man wakes his wife and prays during the night or they pray two rak’at together, they will be recorded among those (men and women) who (constantly) make remembrance of Allah.” This is related by Abu Dawud and others with a sahih chain.
Umm Salamah narrates that the Prophet sallallahu alehi wasallam got up during the night and said: “Glory be to Allah. What trials are descended with the night. And what has descended of treasures. Who will waken the lady occupants of the rooms (i.e., his wives) for prayers; how many a well dressed in this world will be naked in the hereafter.” This is related by al-Bukhari
Al-Bukhari and Muslim record that the Messenger of Allah asked ‘Ali and Fatimah: “Do you not pray [during the night]?” ‘Ali said: “O Messenger of Allah, we are in Allah’s hands. If He wishes to make us get up, we get up.” The Prophet turned away when he said that. Then, they could hear him striking his thigh and saying: “Verily, man disputes a lot.” This is related by al-Bukhari and Muslim.
