Narrated Abu Huraira: Allah's Apostle said, "Angels come to you in succession by night and day and all of them get together at the time of the Fajr and `Asr 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."

Narrated Abu Huraira: The Prophet said, "Angels keep on descending from and ascending to the Heaven in turn, some at night and some by daytime, and all of them assemble together at the time of the Fajr and `Asr prayers. Then those who have stayed with you over-night, ascent unto Allah Who asks them, and He knows the answer better than they, "How have you left My slaves?" They reply, "We have left them praying as we found them praying." If anyone of you says "Amin" (during the Prayer at the end of the recitation of Surat-al-Faitiha), and the angels in Heaven say the same, and the two sayings coincide, all his past sins will be forgiven."

Narrated Abu Huraira: Allah's Apostle said, "(A group of) angels stay with you at night and (another group of) angels by daytime, and both groups gather at the time of the 'Asr and Fajr prayers. Then those angels who have stayed with you overnight, ascend (to Heaven) and Allah asks them (about you) ---- and He knows everything about you. "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.' "

Narrated Abu Huraira: Allah's Apostle said, "There are angels coming to you in succession at night, and others during the day, and they all gather at the time of `Asr and Fajr prayers. Then the angels who have stayed with you overnight ascend (to the heaven) and He (Allah) asks them though He perfectly knows their affairs. 'In what state have you left my slaves?' They say, 'When we left them, they were praying and when we came to them they were praying.' "
