Sahih Bukhari
حَدَّثَنَا مُوسَى، حَدَّثَنَا جَرِيرٌ، حَدَّثَنَا أَبُو رَجَاءٍ، عَنْ سَمُرَةَ، قَالَ قَالَ النَّبِيُّ صلى الله عليه وسلم " رَأَيْتُ اللَّيْلَةَ رَجُلَيْنِ أَتَيَانِي قَالاَ الَّذِي يُوقِدُ النَّارَ مَالِكٌ خَازِنُ النَّارِ، وَأَنَا جِبْرِيلُ، وَهَذَا مِيكَائِيلُ ".
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."
