Abu Huraira reported:The Messenger of Allah (ﷺ) said: Angels take turns among you by night and by day, and they all assemble at the dawn and afternoon prayers. Those (of the angels) who spend the night among you, then, ascend, and their Lord asks them, though He is the best informed about them: How did you leave My servants? -they say: We left them while they were praying and we came to them while they were praying.
حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، قَالَ قَرَأْتُ عَلَى مَالِكٍ عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " يَتَعَاقَبُونَ فِيكُمْ مَلاَئِكَةٌ بِاللَّيْلِ وَمَلاَئِكَةٌ بِالنَّهَارِ وَيَجْتَمِعُونَ فِي صَلاَةِ الْفَجْرِ وَصَلاَةِ الْعَصْرِ ثُمَّ يَعْرُجُ الَّذِينَ بَاتُوا فِيكُمْ فَيَسْأَلُهُمْ رَبُّهُمْ وَهُوَ أَعْلَمُ بِهِمْ كَيْفَ تَرَكْتُمْ عِبَادِي فَيَقُولُونَ تَرَكْنَاهُمْ وَهُمْ يُصَلُّونَ وَأَتَيْنَاهُمْ وَهُمْ يُصَلُّونَ " .
