Ibn ’Umar (RAA) narrated, ‘Some of the companions of the Prophet (ﷺ) were shown in their dreams that the night of Qadr was in the last seven nights of Ramadan. The Messenger of Allah (ﷺ) said to them, “It seems that all of your dreams agree that (the Night of Qadr) is in the last seven nights, and whoever wants to seek that night should do so in the last seven nights (of Ramadan)." Agreed upon.

وَعَنْ اِبْنِ عُمَرَ رَضِيَ اَللَّهُ عَنْهُمَا: { أَنَّ رِجَالاً مِنْ أَصْحَابِ اَلنَّبِيِّ ‏- صلى الله عليه وسلم ‏-أُرُوا لَيْلَةَ اَلْقَدْرِ فِي اَلْمَنَامِ, فِي اَلسَّبْعِ اَلْأَوَاخِرِ, فَقَالَ رَسُولُ اَللَّهِ ‏- صلى الله عليه وسلم ‏-"أَرَى [1]‏ رُؤْيَاكُمْ قَدْ تَوَاطَأَتْ فِي اَلسَّبْعِ اَلْأَوَاخِرِ, فَمَنْ كَانَ مُتَحَرِّيَهَا فَلْيَتَحَرَّهَا فِي اَلسَّبْعِ اَلْأَوَاخِرِ } مُتَّفَقٌ عَلَيْهِ [2]‏ .‏
