(7) بَابُ إِذَا قَالَ أَحَدُكُمْ آمِينَ. وَالْمَلاَئِكَةُ فِي السَّمَاءِ، فَوَافَقَتْ إِحْدَاهُمَا الأُخْرَى، غُفِرَ لَهُ مَا تَقَدَّمَ مِنْ ذَنْبِهِ
Narrated Samura:
The Prophet (ﷺ) said, "Last night I saw (in a dream) two men coming to me. One of them said, "The person who kindles the fire is Malik, the gate-keeper of the (Hell) Fire, and I am Gabriel, and this is Michael."
