the Prophet used to encourage praying Qiyam Al-Lail in Ramadan, but not forcibly. And he said: "When Ramadan begins, the gates of Paradise are opened and the gates of Hell are close, and the devils are chained up." Ibn Al-Mubarak narrated it in Mursal from:  

أَنَّ النَّبِيَّ ﷺ كَانَ يُرَغِّبُ فِي قِيَامِ رَمَضَانَ مِنْ غَيْرِ عَزِيمَةٍ وَقَالَ إِذَا دَخَلَ رَمَضَانُ فُتِّحَتْ أَبْوَابُ الْجَنَّةِ وَغُلِّقَتْ أَبْوَابُ الْجَحِيمِ وَسُلْسِلَتْ فِيهِ الشَّيَاطِينُ أَرْسَلَهُ ابْنُ الْمُبَارَكِ  

"When Ramadan begins, the gates of mercy are opened and the gates of Hall are closed, and the devils are chained up."  

عَنِ النَّبِيِّ ﷺ قَالَ إِذَا دَخَلَ رَمَضَانُ فُتِّحَتْ أَبْوَابُ الرَّحْمَةِ وَغُلِّقَتْ أَبْوَابُ جَهَنَّمَ وَسُلْسِلَتِ الشَّيَاطِينُ  

"The Messenger of Allah said: 'There has come to you Ramadan, a blessed month, which Allah, the Mighty and Sublime, has enjoined you to fast. In it the gates of heavens are opened and the gates of Hell are closed, and every devil is chained up. In it Allah has a night which is better than a thousand months; whoever is deprived of its goodness is indeed deprived."'  

قَالَ رَسُولُ اللَّهِ ﷺ أَتَاكُمْ رَمَضَانُ شَهْرٌ مُبَارَكٌ فَرَضَ اللَّهُ ﷻ عَلَيْكُمْ صِيَامَهُ تُفْتَحُ فِيهِ أَبْوَابُ السَّمَاءِ وَتُغْلَقُ فِيهِ أَبْوَابُ الْجَحِيمِ وَتُغَلُّ فِيهِ مَرَدَةُ الشَّيَاطِينِ لِلَّهِ فِيهِ لَيْلَةٌ خَيْرٌ مِنْ أَلْفِ شَهْرٍ مَنْ حُرِمَ خَيْرَهَا فَقَدْ حُرِمَ  

'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!"'  

مَا تَذْكُرُونَ قُلْنَا شَهْرَ رَمَضَانَ قَالَ سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ تُفْتَحُ فِيهِ أَبْوَابُ الْجَنَّةِ وَتُغْلَقُ فِيهِ أَبْوَابُ النَّارِ وَتُغَلُّ فِيهِ الشَّيَاطِينُ وَيُنَادِي مُنَادٍ كُلَّ لَيْلَةٍ يَا بَاغِيَ الْخَيْرِ هَلُمَّ وَيَا بَاغِيَ الشَّرِّ أَقْصِرْ قَالَ أَبُو عَبْدِ الرَّحْمَنِ هَذَا خَطَأٌ  

" I was in a house with 'Utbah bin Farqad, and I wanted to narrate a Hadith, but there was a man from among the Companions of the Prophet there, and I felt it was more appropriate fro him to narrate the Hadith than I. The man narrated that the Prophet said. Concerning of the Prophet there, and I felt it was more appropriate for him to narrate the Hadith than I. the man narrated that the Prophet said, concerning Ramadan: 'In it the gates of Heavens are opened and the gates of the Fire are shut, and every devil is fettered. A caller calls out every night: O seeker of good, proceed; O seeker of evil, desist!"'  

أَنْ أُحَدِّثَ بِحَدِيثٍ وَكَانَ رَجُلٌ مِنْ أَصْحَابِ النَّبِيِّ ﷺ كَأَنَّهُ أَوْلَى بِالْحَدِيثِ مِنِّي فَحَدَّثَ الرَّجُلُ عَنِ النَّبِيِّ ﷺ قَالَ فِي رَمَضَانَ تُفْتَحُ فِيهِ أَبْوَابُ السَّمَاءِ وَتُغْلَقُ فِيهِ أَبْوَابُ النَّارِ وَيُصَفَّدُ فِيهِ كُلُّ شَيْطَانٍ مَرِيدٍ وَيُنَادِي مُنَادٍ كُلَّ لَيْلَةٍ يَا طَالِبَ الْخَيْرِ هَلُمَّ وَيَا طَالِبَ الشَّرِّ أَمْسِكْ
