Sahih Muslim Book - 5, Hadith - 1432

حَدَّثَنَا يَحْيَى بْنُ يَحْيَى قَالَ قَرَأْتُ عَلَى مَالِكٍ عَنْ أَبِى الزِّنَادِ عَنِ الأَعْرَجِ عَنْ أَبِى هُرَيْرَةَ أَنَّ رَسُولَ اللَّهِ -صلى الله عليه وسلم- قَالَ « يَتَعَاقَبُونَ فِيكُمْ مَلاَئِكَةٌ بِاللَّيْلِ وَمَلاَئِكَةٌ بِالنَّهَارِ وَيَجْتَمِعُونَ فِى صَلاَةِ الْفَجْرِ وَصَلاَةِ الْعَصْرِ ثُمَّ يَعْرُجُ الَّذِينَ بَاتُوا فِيكُمْ فَيَسْأَلُهُمْ رَبُّهُمْ وَهُوَ أَعْلَمُ بِهِمْ كَيْفَ تَرَكْتُمْ عِبَادِى فَيَقُولُونَ تَرَكْنَاهُمْ وَهُمْ يُصَلُّونَ وَأَتَيْنَاهُمْ وَهُمْ يُصَلُّونَ ».

It was narrated from Abu Hurairah that the Messenger of Allah (s.a.w) said: "The Angels of the night and the day come to you in succession, and they meet at the Fajr prayer and at the 'Asr prayer. Then those who stayed among you ascend and their Lord asks them, although He knows best about them, 'How did you leave My slaves?' and they say: 'We left them while they were praying, and we came to them while they were praying."'
