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-Ashari reported that the Messenger of God, peace and blessings be upon him, said: In Paradise there are chambers whose exterior can be seen from their interior and whose interior can be seen from their exterior. God has prepared them for those who speak gently, provide food, fast regularly, and pray at night while people are asleep. Al-Bayhaqi transmitted it in Shuab al-Iman. Al-Tirmidhi transmitted something similar from Ali, and his version says: for those who speak good words.
