وَحَدَّثَنَا مُحَمَّدُ بْنُ حَاتِمٍ وَابْنُ أَبِى عُمَرَ كِلاَهُمَا عَنِ ابْنِ عُيَيْنَةَ - قَالَ ابْنُ حَاتِمٍ حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ - عَنْ عَبْدَةَ وَعَاصِمِ بْنِ أَبِى النَّجُودِ سَمِعَا زِرَّ بْنَ حُبَيْشٍ يَقُولُ سَأَلْتُ أُبَىَّ بْنَ كَعْبٍ - رضى الله عنه - فَقُلْتُ إِنَّ أَخَاكَ ابْنَ مَسْعُودٍ يَقُولُ مَنْ يَقُمِ الْحَوْلَ يُصِبْ لَيْلَةَ الْقَدْرِ. فَقَالَ رَحِمَهُ اللَّهُ أَرَادَ أَنْ لاَ يَتَّكِلَ النَّاسُ أَمَا إِنَّهُ قَدْ عَلِمَ أَنَّهَا فِى رَمَضَانَ وَأَنَّهَا فِى الْعَشْرِ الأَوَاخِرِ وَأَنَّهَا لَيْلَةُ سَبْعٍ وَعِشْرِينَ. ثُمَّ حَلَفَ لاَ يَسْتَثْنِى أَنَّهَا لَيْلَةُ سَبْعٍ وَعِشْرِينَ فَقُلْتُ بِأَىِّ شَىْءٍ تَقُولُ ذَلِكَ يَا أَبَا الْمُنْذِرِ قَالَ بِالْعَلاَمَةِ أَوْ بِالآيَةِ الَّتِى أَخْبَرَنَا رَسُولُ اللَّهِ -صلى الله عليه وسلم- أَنَّهَا تَطْلُعُ يَوْمَئِذٍ لاَ شُعَاعَ لَهَا.
