[Machine] I asked the Messenger of Allah ﷺ which night is the most rewarding, and Sufyan replied, "I heard him say, 'The last third of the night.' And whoever frees a slave, Allah will free every limb of his from the Fire of Hell.'"  

سَأَلْتُ رَسُولَ اللهِ ﷺ أَيُّ اللَّيْلِ أَجْوَبُ؟ وَقَالَ سُفْيَانُ مَرَّةً أَسْمَعُ قَالَ جَوْفُ اللَّيْلِ الْآخِرِ وَمَنْ أَعْتَقَ رَقَبَةً أَعْتَقَ اللهُ بِكُلِّ عُضْوٍ مِنْهَا عُضْوًا مِنْهُ مِنَ النَّارِ  

[Machine] I said, "O Messenger of Allah, which part of the night is most virtuous?" He said, "The last third of the night." I said, "Then which prayer is the most beloved to Allah?" He said, "The prayer offered during the last part of the night, except if it occurs after the pre-dawn prayer (Fajr)." I said, "No prayer after pre-dawn prayer?" He replied, "No, except if you are offering voluntary prayers." Then he said, "Indeed, when you wash your face, sins fall from your face. And when you wash your hands, sins fall from your hands. And when you wash your feet, sins fall from your feet."  

قُلْتُ يَا رَسُولَ اللهِ أَيُّ اللَّيْلِ أَسْمَعُ؟ قَالَ جَوْفُ اللَّيْلِ الْآخِرِ قَالَ ثُمَّ قَالَ ثُمَّ الصَّلَاةُ مَقْبُولَةٌ حَتَّى يُصَلَّى الْفَجْرُ ثُمَّ لَا صَلَاةَ حَتَّى تَكُونَ الشَّمْسُ قِيدَ رُمْحٍ أَوْ رُمْحَيْنِ ثُمَّ الصَّلَاةُ مَقْبُولَةٌ حَتَّى يَقُومَ الظِّلُّ قِيَامَ الرُّمْحِ ثُمَّ لَا صَلَاةَ حَتَّى تَزُولَ الشَّمْسُ ثُمَّ الصَّلَاةُ مَقْبُولَةٌ حَتَّى تَكُونَ الشَّمْسُ قِيدَ رُمْحٍ أَوْ رُمْحَيْنِ ثُمَّ لَا صَلَاةَ حَتَّى تَغْرُبَ الشَّمْسُ قَالَ إِذَا غَسَلْتَ وَجْهَكَ خَرَجَتْ خَطَايَاكَ مِنْ وَجْهِكَ وَإِذَاغَسَلْتَ يَدَيْكَ خَرَجَتْ خَطَايَاكَ مِنْ يَدَيْكَ وَإِذَا غَسَلْتَ رِجْلَيْكَ خَرَجَتْ خَطَايَاكَ مِنْ رِجْلَيْكَ
