And the Messenger of Allah, peace and blessings be upon him, said:“The angels take turns among you by night and by day, and they gather at the prayers of Fajr and Asr. Then those angels who have stayed with you ascend, and Allah, though He knows best about His servants, asks them: ‘In what state did you leave My servants?’ They reply: ‘We left them while they were praying (Fajr), and when we came to them, they were praying (Asr).’”
