Ibn ʿUmar said, "In the lifetime of the Prophet ﷺ I dreamt that a piece of silk cloth was in my hand and it flew with me to whichever part of Paradise I wanted. I also saw as if two persons (i.e. angels) came to me and wanted to take me to Hell. Then an angel met us and told me not to be afraid. He then told them to leave me. Hafsa narrated one of my dreams to the Prophet ﷺ and the Prophet ﷺ said, "Abdullah is a good man. Would that he offer the night prayer (Tahajjud)!" So after that day ʿAbdullah (bin ʿUmar) started offering Tahajjud. The companions of the Prophet ﷺ used to tell him their dreams that (Laila-tul-Qadr) was on the 27th of the month of Ramadan. The Prophet ﷺ said, "I see that your dreams agree on the last ten nights of Ramadan and so whoever is in search of it should seek it in the last ten nights of Ramadan."  

رَأَيْتُ عَلَى عَهْدِ النَّبِيِّ ﷺ كَأَنَّ بِيَدِي قِطْعَةَ إِسْتَبْرَقٍ فَكَأَنِّي لاَ أُرِيدُ مَكَانًا مِنَ الْجَنَّةِ إِلاَّ طَارَتْ إِلَيْهِ وَرَأَيْتُ كَأَنَّ اثْنَيْنِ أَتَيَانِي أَرَادَا أَنْ يَذْهَبَا بِي إِلَى النَّارِ فَتَلَقَّاهُمَا مَلَكٌ فَقَالَ لَمْ تُرَعْ خَلِّيَا عَنْهُ فَقَصَّتْ حَفْصَةُ عَلَى النَّبِيِّ ﷺ إِحْدَى رُؤْيَاىَ فَقَالَ النَّبِيُّ ﷺ نِعْمَ الرَّجُلُ عَبْدُ اللَّهِ لَوْ كَانَ يُصَلِّي مِنَ اللَّيْلِ فَكَانَ عَبْدُ اللَّهِ ؓ يُصَلِّي مِنَ اللَّيْلِ وَكَانُوا لاَ يَزَالُونَ يَقُصُّونَ عَلَى النَّبِيِّ ﷺ الرُّؤْيَا أَنَّهَا فِي اللَّيْلَةِ السَّابِعَةِ مِنَ الْعَشْرِ الأَوَاخِرِ فَقَالَ النَّبِيُّ ﷺ أَرَى رُؤْيَاكُمْ قَدْ تَوَاطَتْ فِي الْعَشْرِ الأَوَاخِرِ فَمَنْ كَانَ مُتَحَرِّيْهَا فَلْيَتَحَرَّهَا مِنَ الْعَشْرِ الأَوَاخِرِ
