Hadith 1104
وَقَالَ اللَّيْثُ : حَدَّثَنِي يُونُسُ ، عَنِ ابْنِ شِهَابٍ ، قَالَ : حَدَّثَنِي عَبْدُ اللَّهِ بْنُ عَامِرِ ، أَنَّ أَبَاهُ أَخْبَرَهُ ، أَنَّهُ " رَأَى النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ صَلَّى السُّبْحَةَ بِاللَّيْلِ فِي السَّفَرِ عَلَى ظَهْرِ رَاحِلَتِهِ حَيْثُ تَوَجَّهَتْ بِهِ " .
Narrated `Abdullah bin Amir that his father had told him that he had seen the Prophet (p.b.u.h) praying Nawafil at night on the back of his Mount on a journey, facing whatever direction it took.
