أَخْبَرَنَا مُحَمَّدُ بْنُ بَشَّارٍ، قَالَ حَدَّثَنَا مُحَمَّدٌ، قَالَ حَدَّثَنَا شُعْبَةُ، عَنْ عَطَاءِ بْنِ السَّائِبِ، عَنْ عَرْفَجَةَ، قَالَ كُنْتُ فِي بَيْتٍ فِيهِ عُتْبَةُ بْنُ فَرْقَدٍ فَأَرَدْتُ أَنْ أُحَدِّثَ بِحَدِيثٍ وَكَانَ رَجُلٌ مِنْ أَصْحَابِ النَّبِيِّ صلى الله عليه وسلم كَأَنَّهُ أَوْلَى بِالْحَدِيثِ مِنِّي فَحَدَّثَ الرَّجُلُ عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏
"‏ فِي رَمَضَانَ تُفْتَحُ فِيهِ أَبْوَابُ السَّمَاءِ وَتُغْلَقُ فِيهِ أَبْوَابُ النَّارِ وَيُصَفَّدُ فِيهِ كُلُّ شَيْطَانٍ مَرِيدٍ وَيُنَادِي مُنَادٍ كُلَّ لَيْلَةٍ يَا طَالِبَ الْخَيْرِ هَلُمَّ وَيَا طَالِبَ الشَّرِّ أَمْسِكْ ‏"‏ ‏.‏
