[Machine] The Messenger of Allah ﷺ said, "The night prayer is performed in pairs, and the odd prayer is performed as a single unit." Abu Abdur Rahman, Khalid ibn Ziyad ibn Jarwan, the upright Khurasani, narrated this Hadith.
قَالَ رَسُولُ اللهِ ﷺ «صَلَاةُ اللَّيْلِ مَثْنَى مَثْنَى وَالْوِتْرُ رَكْعَةً» قَالَ أَبُو عَبْدِ الرَّحْمَنِ خَالِدُ بْنُ زِيَادِ بْنِ جَرْوٍ خُرَاسَانِيٌّ مُسْتَقِيمُ الْحَدِيثِ
