It was narrated from Abu Razin that he heard the Prophet ﷺ say:
“Dreams are attached to the foot of a bird* until they are interpreted, then when they are interpreted they come to pass.” He said: “And dreams are one of the forty-six parts of prophecy.” He (the narrator) said: “And I think he said: ‘(A person) should not tell them except to one whom he loves or one who is wise.’”

حَدَّثَنَا أَبُو بَكْرٍ، حَدَّثَنَا هُشَيْمٌ، عَنْ يَعْلَى بْنِ عَطَاءٍ، عَنْ وَكِيعِ بْنِ عُدُسٍ الْعُقَيْلِيِّ، عَنْ عَمِّهِ أَبِي رَزِينٍ، أَنَّهُ سَمِعَ النَّبِيَّ ﷺ يَقُولُ " الرُّؤْيَا عَلَى رِجْلِ طَائِرٍ مَا لَمْ تُعْبَرْ فَإِذَا عُبِرَتْ وَقَعَتْ " . قَالَ " وَالرُّؤْيَا جُزْءٌ مِنْ سِتَّةٍ وَأَرْبَعِينَ جُزْءًا مِنَ النُّبُوَّةِ " . قَالَ وَأَحْسِبُهُ قَالَ " لاَ يَقُصُّهَا إِلاَّ عَلَى وَادٍّ أَوْ ذِي رَأْىٍ " .
