Narrated Abu Huraira:

Allah's Apostle ﷺ said, "When the Day of Resurrection approaches, the dreams of a believer will hardly fail to come true, and a dream of a believer is one of forty-six parts of prophetism, and whatever belongs to prothetism can never be false." Muhammad bin Sirin said, "But I say this." He said, "It used to be said, 'There are three types of dreams: The reflection of one's thoughts and experiences one has during wakefulness, what is suggested by Satan to frighten the dreamer, or glad tidings from Allah. So, if someone has a dream which he dislikes, he should not tell it to others, but get up and offer a prayer." He added, "He (Abu Huraira) hated to see a Ghul (i.e., iron collar around his neck in a dream) and people liked to see fetters (on their feet in a dream). The fetters on the feet symbolizes one's constant and firm adherence to religion." And Abu 'Abdullah said, "Ghuls (iron collars) are used only for necks."

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ صَبَّاحٍ، حَدَّثَنَا مُعْتَمِرٌ، سَمِعْتُ عَوْفًا، حَدَّثَنَا مُحَمَّدُ بْنُ سِيرِينَ، أَنَّهُ سَمِعَ أَبَا هُرَيْرَةَ، يَقُولُ قَالَ رَسُولُ اللَّهِ ﷺ
" إِذَا اقْتَرَبَ الزَّمَانُ لَمْ تَكَدْ تَكْذِبُ رُؤْيَا الْمُؤْمِنِ، وَرُؤْيَا الْمُؤْمِنِ جُزْءٌ مِنْ سِتَّةٍ وَأَرْبَعِينَ جُزْءًا مِنَ النُّبُوَّةِ. " قَالَ مُحَمَّدٌ وَأَنَا أَقُولُ هَذِهِ قَالَ وَكَانَ يُقَالُ الرُّؤْيَا ثَلاَثٌ حَدِيثُ النَّفْسِ، وَتَخْوِيفُ الشَّيْطَانِ، وَبُشْرَى مِنَ اللَّهِ، فَمَنْ رَأَى شَيْئًا يَكْرَهُهُ فَلاَ يَقُصُّهُ عَلَى أَحَدٍ، وَلْيَقُمْ فَلْيُصَلِّ. قَالَ وَكَانَ يُكْرَهُ الْغُلُّ فِي النَّوْمِ، وَكَانَ يُعْجِبُهُمُ الْقَيْدُ، وَيُقَالُ الْقَيْدُ ثَبَاتٌ فِي الدِّينِ. وَرَوَى قَتَادَةُ وَيُونُسُ وَهِشَامٌ وَأَبُو هِلاَلٍ عَنِ ابْنِ سِيرِينَ عَنْ أَبِي هُرَيْرَةَ عَنِ النَّبِيِّ ﷺ وَأَدْرَجَهُ بَعْضُهُمْ كُلَّهُ فِي الْحَدِيثِ، وَحَدِيثُ عَوْفٍ أَبْيَنُ. وَقَالَ يُونُسُ لاَ أَحْسِبُهُ إِلاَّ عَنِ النَّبِيِّ ﷺ فِي الْقَيْدِ. قَالَ أَبُو عَبْدِ اللَّهِ لاَ تَكُونُ الأَغْلاَلُ إِلاَّ فِي الأَعْنَاقِ.
