حَدَّثَنَا أَبُو بَدْرٍ، عَبَّادُ بْنُ الْوَلِيدِ حَدَّثَنَا مُحَمَّدُ بْنُ بِلاَلٍ، حَدَّثَنَا عِمْرَانُ الْقَطَّانُ، عَنْ قَتَادَةَ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ دَخَلَ رَمَضَانُ فَقَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ ‏"‏ إِنَّ هَذَا الشَّهْرَ قَدْ حَضَرَكُمْ وَفِيهِ لَيْلَةٌ خَيْرٌ مِنْ أَلْفِ شَهْرٍ مَنْ حُرِمَهَا فَقَدْ حُرِمَ الْخَيْرَ كُلَّهُ وَلاَ يُحْرَمُ خَيْرَهَا إِلاَّ مَحْرُومٌ ‏"‏ ‏.‏
