It was narrated from Abu ‘Ubaidullah Muslim bin Mishkam, that ‘Awf bin Malik narrated that the Messenger of Allah ﷺ said:
“Dreams are of three types: Some are terrifying things from Satan, aimed at causing grief to the son of Adam; some are things that a person is concerned with when he is awake, so he sees them in his dreams; and some are a part of the forty-six parts of prophecy.” He said: “I said to him: ‘Did you hear this from the Messenger of Allah ﷺ?’ He said: ‘Yes, I heard it from the Messenger of Allah ﷺ, I heard it from the Messenger of Allah ﷺ.’”

حَدَّثَنَا هِشَامُ بْنُ عَمَّارٍ، حَدَّثَنَا يَحْيَى بْنُ حَمْزَةَ، حَدَّثَنَا يَزِيدُ بْنُ عَبِيدَةَ، حَدَّثَنِي أَبُو عُبَيْدِ اللَّهِ، مُسْلِمُ بْنُ مِشْكَمٍ عَنْ عَوْفِ بْنِ مَالِكٍ، عَنْ رَسُولِ اللَّهِ ـ ﷺ ـ قَالَ " إِنَّ الرُّؤْيَا ثَلاَثٌ مِنْهَا أَهَاوِيلُ مِنَ الشَّيْطَانِ لِيَحْزُنَ بِهَا ابْنَ آدَمَ وَمِنْهَا مَا يَهُمُّ بِهِ الرَّجُلُ فِي يَقَظَتِهِ فَيَرَاهُ فِي مَنَامِهِ وَمِنْهَا جُزْءٌ مِنْ سِتَّةٍ وَأَرْبَعِينَ جُزْءًا مِنَ النُّبُوَّةِ " . قَالَ قُلْتُ لَهُ أَنْتَ سَمِعْتَ هَذَا مِنْ رَسُولِ اللَّهِ ـ ﷺ ـ قَالَ نَعَمْ أَنَا سَمِعْتُهُ مِنْ رَسُولِ اللَّهِ ـ ﷺ ـ أَنَا سَمِعْتُهُ مِنْ رَسُولِ اللَّهِ ـ ﷺ ـ .
