Encouragement to get up during the Night - Section 2
وَعَنْ أَبِي مَالِكٍ الْأَشْعَرِيِّ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «إِنَّ فِي الْجَنَّةِ غُرَفًا يُرَى ظَاهِرُهَا مِنْ بَاطِنِهَا وَبَاطِنُهَا مِنْ ظَاهِرِهَا أَعَدَّهَا اللَّهُ لِمَنْ أَلَانَ الْكَلَامَ وَأَطْعَمَ الطَّعَامَ وَتَابَعَ الصِّيَامَ وَصَلَّى بِاللَّيْلِ وَالنَّاسُ نيام» . رَوَاهُ الْبَيْهَقِيّ فِي شعب الْإِيمَان وَرَوَى التِّرْمِذِيُّ عَنْ عَلِيٍّ نَحْوَهُ وَفِي رِوَايَتِهِ: «لمن أطاب الْكَلَام»
Abu Malik al-Ash‘ari reported God’s Messenger as saying, “In paradise there are rooms the outside of which can be seen from within and the inside from without which God has prepared for those who speak gently, provide food, observe frequent fasting, and pray during the night when people are asleep.” Baihaqi transmitted it in Shu'ab al-iman and Tirmidhi transmitted something similar from ‘Ali. In his version it says “for those who speak pleasantly.”
