حَدَّثَنَا مُسَدَّدٌ ، قَالَ : حَدَّثَنَا بِشْرُ بْنُ الْمُفَضَّلِ ، عَنْ عُبَيْدُ اللَّهِ ، عَنْ نَافِعٍ ، عَنْ ابْنِ عُمَرَ ، قَالَ : سَأَلَ رَجُلٌ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَهُوَ عَلَى الْمِنْبَرِ ، مَا تَرَى فِي صَلَاةِ اللَّيْلِ ؟ قَالَ : " مَثْنَى مَثْنَى ، فَإِذَا خَشِيَ الصُّبْحَ صَلَّى وَاحِدَةً فَأَوْتَرَتْ لَهُ مَا صَلَّى ، وَإِنَّهُ كَانَ يَقُولُ : اجْعَلُوا آخِرَ صَلَاتِكُمْ وِتْرًا ، فَإِنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَمَرَ بِهِ " .
Narrated Nafi`: Ibn `Umar said, "While the Prophet was on the pulpit, a man asked him how to offer the night prayers. He replied, 'Pray two rak`at at a time and then two and then two and so on, and if you are afraid of the dawn (the approach of the time of the Fajr prayer) pray one rak`a and that will be the witr for all the rak`at which you have offered." Ibn `Umar said, "The last rak`at of the night prayer should be odd, for the Prophet ordered it to be so.

Hadith 473
حَدَّثَنَا أَبُو النُّعْمَانِ ، قَالَ : حَدَّثَنَا حَمَّادُ ، عَنْ أَيُّوبَ ، عَنْ نَافِعٍ ، عَنِ ابْنِ عُمَرَ ، أَنَّ رَجُلًا جَاءَ إِلَى النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَهُوَ يَخْطُبُ ، فَقَالَ : كَيْفَ صَلَاةُ اللَّيْلِ ؟ فَقَالَ : " مَثْنَى مَثْنَى ، فَإِذَا خَشِيتَ الصُّبْحَ فَأَوْتِرْ بِوَاحِدَةٍ تُوتِرُ لَكَ مَا قَدْ صَلَّيْتَ " ، قَالَ الْوَلِيدُ بْنُ كَثِيرٍ : حَدَّثَنِي عُبَيْدُ اللَّهِ بْنُ عَبْدِ اللَّهِ ، أَنَّ ابْنَ عُمَرَ حَدَّثَهُمْ ، أَنَّ رَجُلًا نَادَى النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَهُوَ فِي الْمَسْجِدِ .

Hadith 474
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ ، قَالَ : أَخْبَرَنَا مَالِكٌ ، عَنْ إِسْحَاقَ بْنِ عَبْدِ اللَّهِ بْنِ أَبِي طَلْحَةَ ، أَنَّ أَبَا مُرَّةَ مَوْلَى عَقِيلِ بْنِ أَبِي طَالِبٍ أَخْبَرَهُ ، عَنْ أَبِي وَاقِدٍ اللَّيْثِيِّ ، قَالَ : بَيْنَمَا رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فِي الْمَسْجِدِ ، فَأَقْبَلَ ثَلَاثَةُ نَفَرٍ ، فَأَقْبَلَ اثْنَانِ إِلَى رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَذَهَبَ وَاحِدٌ ، فَأَمَّا أَحَدُهُمَا فَرَأَى فُرْجَةً فَجَلَسَ ، وَأَمَّا الْآخَرُ فَجَلَسَ خَلْفَهُمْ ، فَلَمَّا فَرَغَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ، قَالَ : " أَلَا أُخْبِرُكُمْ عَنِ الثَّلَاثَةِ ، أَمَّا أَحَدُهُمْ فَأَوَى إِلَى اللَّهِ فَآوَاهُ اللَّهُ ، وَأَمَّا الْآخَرُ فَاسْتَحْيَا فَاسْتَحْيَا اللَّهُ مِنْهُ ، وَأَمَّا الْآخَرُ فَأَعْرَضَ فَأَعْرَضَ اللَّهُ عَنْهُ " .
Narrated Abu Waqid al-Laithi: While Allah's Apostle was sitting in the mosque (with some people) three men came, two of them came in front of Allah's Apostle and the third one went away, and then one of them found a place in the circle and sat there while the second man sat behind the gathering, and the third one went away. When Allah's Apostle finished his preaching, he said, "Shall I tell you about these three persons? One of them betook himself to Allah and so Allah accepted him and accommodated him; the second felt shy before Allah so Allah did the same for him and sheltered him in His Mercy (and did not punish him), while the third turned his face from Allah, and went away, so Allah turned His face from him likewise.
