حَدَّثَنَا إِسْمَاعِيلُ أَخْبَرَنَا أَيُّوبُ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ قَالَ كَانَ النَّاسُ يَرَوْنَ الرُّؤْيَا فَيَقُصُّونَهَا عَلَى رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَالَ إِنِّي أَوْ قَالَ أَسْمَعُ رُؤْيَاكُمْ قَدْ تَوَاطَأَتْ عَلَى السَّبْعِ الْأَوَاخِرِ فَمَنْ كَانَ مِنْكُمْ مُتَحَرِّيَهَا فَلْيَتَحَرَّهَا فِي السَّبْعِ الْأَوَاخِرِ
مسند امام احمد بن حنبل · Hadith 4499
It was narrated that Ibn Umar said: The people would see dreams then tell the Messenger of Allah (PBUH) about them. He said: "I think - or I hear - that your drains all together refer to the last seven nights (of Ramadan). whoever among you wants to Seek it (Laylat al-Qadr), let him it in the last seven nights."
