Arabic (Original)
حَدَّثَنَا هَاشِمٌ حَدَّثَنَا اللَّيْثُ حَدَّثَنِي نَافِعٌ عَنْ عَبْدِ اللَّهِ عَنْ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَنَّهُ قَالَ صَلَاةُ اللَّيْلِ مَثْنَى مَثْنَى فَإِذَا خِفْتَ الصُّبْحَ فَأَوْتِرْ بِوَاحِدَةٍ وَاجْعَلْ آخِرَ صَلَاتِكَ وِتْرًا.
English Translation
Hashim told us, al-Layth told us, Nafi' told me, from Abdullah, from the Messenger of Allah, peace and blessings be upon him, that he said: "The night prayer is [performed] two by two; so when one of you fears the approach of dawn, let him pray one rak'ah as witr, making the last of his prayer witr."
