The virtue of Lailat Al-Qadr and the Exhortation to seek it; When it is and the most likely times to seek it
Sahih Muslim
وَحَدَّثَنِي حَرْمَلَةُ بْنُ يَحْيَى، أَخْبَرَنَا ابْنُ وَهْبٍ، أَخْبَرَنِي يُونُسُ، عَنِ ابْنِ شِهَابٍ، أَخْبَرَنِي سَالِمُ بْنُ عَبْدِ اللَّهِ بْنِ عُمَرَ، أَنَّ أَبَاهُ، - رضى الله عنه - قَالَ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ لِلَيْلَةِ الْقَدْرِ " إِنَّ نَاسًا مِنْكُمْ قَدْ أُرُوا أَنَّهَا فِي السَّبْعِ الأُوَلِ وَأُرِيَ نَاسٌ مِنْكُمْ أَنَّهَا فِي السَّبْعِ الْغَوَابِرِ فَالْتَمِسُوهَا فِي الْعَشْرِ الْغَوَابِرِ " .
Salim b. 'Abdullah b. 'Umar reported that his father said: I heard Allah's Messenger (ﷺ) as saying: So far as Lailat-ul-Qadr is concerned. some persons among you have seen it (in a dream) in the first week and some persons among you have been shown that it is in the last week; so seek it in the last ten (nights).
