9) باب يَنْزِلُ لِلْمَكْتُوبَةِ

حَدَّثَنَا يَحْيَى بْنُ بُكَيْرٍ، قَالَ حَدَّثَنَا اللَّيْثُ، عَنْ عُقَيْلٍ، عَنِ ابْنِ شِهَابٍ، عَنْ عَبْدِ اللَّهِ بْنِ عَامِرِ بْنِ رَبِيعَةَ، أَنَّ عَامِرَ بْنَ رَبِيعَةَ، أَخْبَرَهُ قَالَ رَأَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم وَهْوَ عَلَى الرَّاحِلَةِ يُسَبِّحُ، يُومِئُ بِرَأْسِهِ قِبَلَ أَىِّ وَجْهٍ تَوَجَّهَ، وَلَمْ يَكُنْ رَسُولُ اللَّهِ صلى الله عليه وسلم يَصْنَعُ ذَلِكَ فِي الصَّلاَةِ الْمَكْتُوبَةِ‏.‏
