وَعَنْ أَبِي سَعِيدٍ وَأَبِي هُرَيْرَةَ قَالَا: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «إِذا أَيْقَظَ الرَّجُلُ أَهْلَهُ مِنَ اللَّيْلِ فَصَلَّيَا أَوْ صَلَّى رَكْعَتَيْنِ جَمِيعًا كُتِبَا فِي الذَّاكِرِينَ وَالذَّاكِرَاتِ» . رَوَاهُ أَبُو دَاوُد وَابْن مَاجَه
Abu Sa'id and Abu Huraira reported God’s Messenger as saying, “When a man wakens his wife* during the night and they pray (or he prays) two rak'as together, they are recorded among the men and women who make mention of God.” * The Arabic word is ahl which means “people” or “family”, and sometimes "wife. As the dual is used about them praying together, it obviously means “wife” here; but in Ibn ‘Umar’s tradition below the plural is used, and so the word is there translated “family”. Abu Dawud and Ibn Majah transmitted it.
