The Prophet ﷺ said: When a man himself wakes at night and wakens his wife and they pray two rak'ahs together, they are recorded among the men and women who make much mention of Allah. (Using translation from Abū Dāʾūd 1451)
قَالَ رَسُولُ اللَّهِ ﷺ «مَنِ اسْتَيْقَظَ مِنَ اللَّيْلِ وَأَيْقَظَ أَهْلَهُ فَصَلَّيَا رَكْعَتَيْنِ جَمِيعًا كُتِبَا مِنَ الذَّاكِرِينَ اللَّهَ كَثِيرًا وَالذَّاكِرَاتِ»
