أَخْبَرَنَا الْحَسَنُ بْنُ مُحَمَّدٍ، عَنْ عَفَّانَ، قَالَ حَدَّثَنَا هَمَّامٌ، قَالَ حَدَّثَنَا قَتَادَةُ، عَنْ عَبْدِ اللَّهِ بْنِ شَقِيقٍ، عَنِ ابْنِ عُمَرَ، أَنَّ رَجُلاً، مِنْ أَهْلِ الْبَادِيَةِ سَأَلَ رَسُولَ اللَّهِ صلى الله عليه وسلم عَنْ صَلاَةِ اللَّيْلِ قَالَ ‏
"‏ مَثْنَى مَثْنَى وَالْوَتْرُ رَكْعَةٌ مِنْ آخِرِ اللَّيْلِ ‏"‏ ‏.‏
