حَدَّثَنَا عَبْدُ اللَّهِ بْنُ سَعِيدٍ، حَدَّثَنَا ابْنُ أَبِي غَنِيَّةَ، حَدَّثَنَا الأَعْمَشُ، عَنْ أَبِي سُفْيَانَ، عَنْ جَابِرٍ، عَنْ رَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ قَالَ " مَنْ خَافَ مِنْكُمْ أَنْ لاَ يَسْتَيْقِظَ مِنْ آخِرِ اللَّيْلِ فَلْيُوتِرْ مِنْ أَوَّلِ اللَّيْلِ ثُمَّ لْيَرْقُدْ وَمَنْ طَمِعَ مِنْكُمْ أَنْ يَسْتَيْقِظَ مِنْ آخِرِ اللَّيْلِ فَلْيُوتِرْ مِنْ آخِرِ اللَّيْلِ فَإِنَّ قِرَاءَةَ آخِرِ اللَّيْلِ مَحْضُورَةٌ وَذَلِكَ أَفْضَلُ " .
