‘Umara b. Ruwaiba said that he heard God's Messenger say, “No one will enter hell who has prayed before the rising of the sun and before its setting," meaning the dawn and the afternoon prayer.
Narrated Abu Huraira reported God’s Messenger as saying:
Angels take turns among you by night and by day, and they all assemble at the dawn and the afternoon prayers. Those who spent the night among you then ascend, and their Lord asks them, yet He is best informed about them, “How did you leave My servants?” They reply, “We left them while they were praying, and we came to them while they were praying.”
Jundub al-Qasri reported God’s Messenger as saying, “When anyone prays the morning prayer he is in God’s protection; so see that God does not call you to account for withdrawing in any respect from His protection, for if He does this to anyone for any cause He will catch him and turn him over on his face in the fire of Jahannam.”
Muslim transmitted it. Some MSS. of al-Masabih have al-Qushair instead of al-Qasri.
