Mishkat al-Masabih 4 Prayer كتاب الصلاة 638

وَعَن أم سَلمَة قَالَتْ: اسْتَيْقَظَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لَيْلَةً فَزِعًا يَقُولُ: «سُبْحَانَ اللَّهِ مَاذَا أُنْزِلَ اللَّيْلَةَ مِنَ الْخَزَائِنِ؟ وَمَاذَا أُنْزِلَ مِنَ الْفِتَنِ؟ مَنْ يُوقِظُ صَوَاحِبَ الْحُجُرَاتِ» يُرِيدُ أَزْوَاجَهُ «لِكَيْ يُصَلِّينَ؟ رُبَّ كَاسِيَةٍ فِي الدُّنْيَا عَارِيَةٍ فِي الْآخِرَة» أخرجه البُخَارِيّ

Umm Salama said that God’s Messenger awoke one night with a start and said, “Glory be to God. What treasures have been sent down tonight, and what trials have been sent down! Who will waken those who are in the inner chambers (meaning his wives) in order that they may pray? Many a woman who is clothed in this world will be naked in the next.” Bukhari transmitted it.
