And al-Bukhari & narrated from Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said:
"Angels come to you in succession by night and by day, and they meet at Fajr prayer and at 'Asr prayer, then those who stayed among you ascend, and He (Allah) asks them, although He knows best, 'How did you leave My slaves?' They say: ‘We left them when they were praying and we came to them when they were praying.”
