Arabic (Original)
حَدَّثَنَا يَزِيدُ أَخْبَرَنَا سُلَيْمَانُ التَّيْمِيُّ عَنْ طَاوُسٍ عَنِ ابْنِ عُمَرَ عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ صَلَاةُ اللَّيْلِ مَثْنَى مَثْنَى فَإِذَا خِفْتَ الصُّبْحَ فَأَوْتِرْ بِوَاحِدَةٍ.
English Translation
Yazid told us, Sulayman al-Taymi informed us, from Tawus, from Ibn 'Umar, from the Prophet, peace and blessings be upon him, who said, "The night prayer is two by two; when you fear the approach of dawn, perform witr with a single rak'ah."
