Sunan Ibn Majah, Volume 2, Book 7, Hadith 1642 (DarusSalam) ⓘ

It was narrated from Abu Hurairah that the Messenger of Allah said: “When the first night of Ramadan comes, the satans and mischievous jinns are chained up, and the gates of the Fire are closed, and none of its gates are opened. The gates of Paradise are opened and none of its gates are closed. And a caller cried out: ‘O seeker of good, proceed, O seeker of evil, stop.’ And Allah has necks (people) whom He frees (from the Fire), and that happens every day.”

حَدَّثَنَا أَبُو كُرَيْبٍ، مُحَمَّدُ بْنُ الْعَلاَءِ حَدَّثَنَا أَبُو بَكْرِ بْنُ عَيَّاشٍ، عَنِ الأَعْمَشِ، عَنْ أَبِي صَالِحٍ، عَنْ أَبِي هُرَيْرَةَ، عَنْ رَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ قَالَ ‏ "‏ إِذَا كَانَتْ أَوَّلُ لَيْلَةٍ مِنْ رَمَضَانَ صُفِّدَتِ الشَّيَاطِينُ وَمَرَدَةُ الْجِنِّ وَغُلِّقَتْ أَبْوَابُ النَّارِ فَلَمْ يُفْتَحْ مِنْهَا بَابٌ وَفُتِحَتْ أَبْوَابُ الْجَنَّةِ فَلَمْ يُغْلَقْ مِنْهَا بَابٌ وَنَادَى مُنَادٍ يَا بَاغِيَ الْخَيْرِ أَقْبِلْ وَيَا بَاغِيَ الشَّرِّ أَقْصِرْ وَلِلَّهِ عُتَقَاءُ مِنَ النَّارِ وَذَلِكَ فِي كُلِّ لَيْلَةٍ ‏" ‏ ‏.‏
