Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "Indeed, Allah Almighty has some angels who come to you in succession, before and after. Then, when the time of Fajr prayer comes, the angels of the day descend and they join you in prayer, and then the angels of the night ascend. And the angels of the day remain with you. Then their Lord asks them, although He knows them well, 'In what state did you leave My servants?' He said that they reply, 'We came to them while they were praying and we left them while they were performing prayer.' Then, when the time of Asr prayer comes, the angels of the night descend and join you in prayer, then the angels of the day ascend and the angels of the night remain with you. He said that then their Lord asks them, although He knows them well, 'In what state did you leave My servants?' He said, I think they say, 'So (O Allah) forgive them on the Day of Resurrection.'"
