Mishkat al-Masabih #582

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.
