أَخْبَرَنَا خَالِدُ بْنُ مَخْلَدٍ ، حَدَّثَنَا مَالِكٌ ، عَنْ نَافِعٍ ، عَنْ ابْنِ عُمَرَ ، قَالَ : سَأَلَ رَجُلٌ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَنْ صَلَاةِ اللَّيْلِ، فَقَالَ :" مَثْنَى مَثْنَى، فَإِذَا خَشِيَ أَحَدُكُمْ الصُّبْحَ، فَلْيُصَلِّ رَكْعَةً وَاحِدَةً تُوتِرُ، مَا قَدْ صَلَّى ".
قِيلَ لِأَبِي مُحَمَّدٍ : تَأْخُذُ بِهِ؟ قَالَ : نَعَمْ

Khalid bin Mukhlid told us, Malik told us, on the authority of Nafi’, on the authority of Ibn Umar, he said: A man asked the Messenger of God, may God bless him and grant him peace, about The night prayer, and he said: “Two by two, so if one of you fears the morning prayer, let him pray one rak’ah of Witr, as long as he has prayed.”
It was said to Abu Muhammad: Do you take him? He said: Yes
