Arabic (Original)
حَدَّثَنَا يَحْيَى عَنْ عُبَيْدِ اللَّهِ أَخْبَرَنِي نَافِعٌ عَنِ ابْنِ عُمَرَ قَالَ سَأَلَ رَجُلٌ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَنْ صَلَاةِ اللَّيْلِ قَالَ يُصَلِّي أَحَدُكُمْ مَثْنَى مَثْنَى فَإِذَا خَشِيَ أَنْ يُصْبِحَ صَلَّى رَكْعَةً تُوتِرُ لَهُ صَلَاتَهُ.
English Translation
Yahya told us, from Ubaydullah: Nafi' informed me, from Ibn Umar, who said: A man asked the Messenger of Allah, peace and blessings be upon him, about the night prayer. He said, "Let one of you pray two by two, and when he fears the approach of dawn, let him pray one rak'ah, which will make his prayer witr."
