Sunan an-Nasa'i, Book 22, Hadith 13 (In-Book) ⓘ
It was narrated form Abu Hurairah that the Prophet said: "When the month of Ramadan beings, the gates of Paradise are opened. The gates of the Fire are closed and the devils are chained up." (Sahih) Abu 'Abdur-Rahman (An-Nasai) said: This meaning, the narration of Ibn Ishaq - is a mistake. Ibn Ishaq did not hear from Az-Zuhri. What is correct is what we mentioned it previously.
أَخْبَرَنَا عُبَيْدُ اللَّهِ بْنُ سَعْدٍ، قَالَ حَدَّثَنَا عَمِّي، قَالَ حَدَّثَنَا أَبِي، عَنِ ابْنِ إِسْحَاقَ، عَنِ الزُّهْرِيِّ، عَنِ ابْنِ أَبِي أَنَسٍ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " إِذَا دَخَلَ شَهْرُ رَمَضَانَ فُتِّحَتْ أَبْوَابُ الْجَنَّةِ وَغُلِّقَتْ أَبْوَابُ النَّارِ وَسُلْسِلَتِ الشَّيَاطِينُ " . قَالَ أَبُو عَبْدِ الرَّحْمَنِ هَذَا - يَعْنِي حَدِيثَ ابْنِ إِسْحَاقَ - خَطَأٌ وَلَمْ يَسْمَعْهُ ابْنُ إِسْحَاقَ مِنَ الزُّهْرِيِّ وَالصَّوَابُ مَا تَقَدَّمَ ذِكْرُنَا لَهُ .
