"I noticed that the Messenger of Allah ﷺ was missing one night, and I thought he had gone to one of his other wives. I tried to feel for him, and I found him bowing or prostrating and saying: 'SubhanakAllahumma wa bihamdika la ilaha ila ant (Glory and praise be to You, O Allah, there is none worthy of worship but You.)'" She said: "May my father and mother be ransomed for you. I thought you were doing one thing and you were doing something else altogether." (Using translation from Nasāʾī 1131)
فَقَدْتُ رَسُولَ اللهِ ﷺ ذَاتَ لَيْلَةٍ فَظَنَنْتُ أَنَّهُ ذَهَبَ إِلَى بَعْضِ نِسَائِهِ فَتَحَسَّسْتُهُ فَإِذَا هُوَ رَاكِعٌ أَوْ سَاجِدٌ يَقُولُ «سُبْحَانَكَ وَبِحَمْدِكَ لَا إِلَهَ إِلَّا أَنْتَ» فَقَالَتْ «بِأَبِي وَأُمِّي إِنَّكَ لَفِي شَأْنٍ وَإِنِّي لَفِي آخَرَ»
