Hadith on Worship: The virtue of waking up at night to perform acts of worship

Umm Salamah reported: The Prophet, peace be upon him, woke her up one night and he said, “Glory be to Allah, what has Allah sent down of trials tonight? What has Allah sent down of treasures? Wake the sleeping occupants of these apartments, O Lord, for perhaps they would be clothed in this world but naked in the Hereafter.”

[Sahih Bukhari, Book 21, Number 226]

عَنْ أُمِّ سَلَمَةَ رَضِيَ اللَّهُ عَنْهَا أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ اسْتَيْقَظَ لَيْلَةً فَقَالَ سُبْحَانَ اللَّهِ مَاذَا أُنْزِلَ اللَّيْلَةَ مِنْ الْفِتْنَةِ مَاذَا أُنْزِلَ مِنْ الْخَزَائِنِ مَنْ يُوقِظُ صَوَاحِبَ الْحُجُرَاتِ يَا رُبَّ كَاسِيَةٍ فِي الدُّنْيَا عَارِيَةٍ فِي الْآخِرَةِ

صحيح البخاري كتاب التَّهَجُّد بَاب تَحْرِيضِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَلَى صَلَاةِ اللَّيْلِ وَالنَّوَافِلِ مِنْ غَيْرِ إِيجَابٍ
