Hadith narrated by Utba ibn Farqad

'The month of Ramadan. He said: "I heard the Messenger of Allah say: In it the gates of Paradise are opened and the gates of the Fire are closed, and the devils are chained up, and a caller calls out every night: O doer of good, proceed; O doer of evil, desist!"'

"‏ تُفْتَحُ فِيهِ أَبْوَابُ الْجَنَّةِ وَتُغْلَقُ فِيهِ أَبْوَابُ النَّارِ وَتُغَلُّ فِيهِ الشَّيَاطِينُ وَيُنَادِي مُنَادٍ كُلَّ لَيْلَةٍ يَا بَاغِيَ الْخَيْرِ هَلُمَّ وَيَا بَاغِيَ الشَّرِّ أَقْصِرْ ‏"
