Messenger of Allah ﷺ said, "Angels come to you in succession by night and day and all of them get together at the time of the Fajr and ʿAsr prayers. Those who have passed the night with you (or stayed with you) ascend (to the Heaven) and Allah asks them, though He knows everything about you, well, "In what state did you leave my slaves?" The angels reply: "When we left them they were praying and when we reached them, they were praying." (Using translation from Bukhārī 555)
أَنَّ رَسُولَ اللهِ ﷺ قَالَ يَتَعَاقَبُونَ فِيكُمْ مَلَائِكَةٌ بِاللَّيْلِ وَمَلَائِكَةٌ بِالنَّهَارِ وَيَجْتَمِعُونَ فِي صَلَاةِ الْفَجْرِ ثُمَّ يَعْرُجُ الَّذِينَ بَاتُوا فِيكُمْ فَيَسْأَلُهُمْ وَهُوَ أَعْلَمُ كَيْفَ تَرَكْتُمْ عِبَادِي؟ فَيَقُولُونَ تَرَكْنَاهُمْ وَهُمْ يُصَلُّونَ وَأَتَيْنَاهُمْ وَهُمْ يُصَلُّونَ اللَّفْظُ لِقُتَيْبَةَ
