'When it is Ramadan, the gates of Paradise are opened, the gates of Hell are closed, and the devils are chained up."' It was narrated by Ibn Ishaq from Az-Zuhri.
قَالَ رَسُولُ اللَّهِ ﷺ إِذَا كَانَ رَمَضَانُ فُتِّحَتْ أَبْوَابُ الْجَنَّةِ وَغُلِّقَتْ أَبْوَابُ جَهَنَّمَ وَسُلْسِلَتِ الشَّيَاطِينُ رَوَاهُ ابْنُ إِسْحَاقَ عَنِ الزُّهْرِيِّ
