حَدَّثَنَا عَبْدُ الرَّحْمَنِ عَنْ سُفْيَانَ عَنْ عَبْدِ اللَّهِ بْنِ دِينَارٍ سَمِعْتُ ابْنَ عُمَرَ يَقُولُ سُئِلَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَنْ لَيْلَةِ الْقَدْرِ فَقَالَ تَحَرَّوْهَا فِي السَّبْعِ الْأَوَاخِرِ
مسند امام احمد بن حنبل · Hadith 5283
It was narrated from Abdullah ibn Dinar: I heard Ibn Umar say: The Messenger of Allah (PBUH) was asked about Laylat al-Qadr and he said: "Seek it in the last seven (nights).”
