وَعَنْ أَبِي هُرَيْرَةَ رَضِيَ اللهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: إِذَا كَانَ أَوَّلُ لَيْلَةٍ مِّنْ شَهْرِ رَمَضَانَ صُفَدَتِ الشَّيَاطِينُ وَمَرَدَةُ الْجِنِّ وَغُلِّقَتْ أَبْوَابُ النَّارِ فَلَمْ يُفْتَحُ مِنْهَا بَابٌ وَفُتِحَتْ أَبْوَابُ الْجَنَّةِ فَلَمْ يُعْلَقَ مِنْهَا بَابٌ وَيُنَادِي مَنَادٍ: يَا بَاغِيَ الْخَيْرِ أَقْبِلُ، وَيَا بَاغِيَ الشَّرِ أَقْصِرُ، وَلِلَّهِ عَتَقَاءُ مِنَ النَّارِ وَذَلِكَ كُلَّ لَيْلَةٍ. رَوَاهُ التَّرْمِذِيُّ وَابْنُ مَاجَهُ
Abu Huraira reported God's messenger as saying, "When the first night of Ramadan comes the devils and the rebellious jinn are chained, the gates of hell are locked and not one of them is opened; the gates of paradise are opened and not one of them is locked, and a crier calls, 'You who desire what is good, come forward, and you who desire evil refrain.' Some are freed from hell by God, and that happens every night." Tirmidhi and Ibn Majah transmitted it.
