Abu Huraira (Allah be pleased with him) reported Allah's Messenger (ﷺ) as saying:I was shown Lailat-ul-Qadr; then some members of my family awoke me up, then I was caused to forget it. So seek it in the last week. Harmala said: (The Prophet did not say:" I was made to forget," but he stated):" But I forgot it."
حَدَّثَنَا أَبُو الطَّاهِرِ، وَحَرْمَلَةُ بْنُ يَحْيَى، قَالاَ أَخْبَرَنَا ابْنُ وَهْبٍ، أَخْبَرَنِي يُونُسُ، عَنِ ابْنِ شِهَابٍ، عَنْ أَبِي سَلَمَةَ بْنِ عَبْدِ الرَّحْمَنِ، عَنْ أَبِي هُرَيْرَةَ، - رضى الله عنه - أَنَّاللَّهِ صلى الله عليه وسلم قَالَ " أُرِيتُ لَيْلَةَ الْقَدْرِ ثُمَّ أَيْقَظَنِي بَعْضُ أَهْلِي فَنُسِّيتُهَا فَالْتَمِسُوهَا فِي الْعَشْرِ الْغَوَابِرِ " . وَقَالَ حَرْمَلَةُ " فَنَسِيتُهَا " .
