حَدَّثَنَا عَبْدَانُ، عَنْ عَبْدِ اللَّهِ، عَنْ إِبْرَاهِيمَ بْنِ طَهْمَانَ، قَالَ حَدَّثَنِي الْحُسَيْنُ الْمُكْتِبُ، عَنِ ابْنِ بُرَيْدَةَ، عَنْ عِمْرَانَ بْنِ حُصَيْنٍ ـ رضى الله عنه ـ قَالَ كَانَتْ بِي بَوَاسِيرُ فَسَأَلْتُ النَّبِيَّ صلى الله عليه وسلم عَنِ الصَّلاَةِ فَقَالَ " صَلِّ قَائِمًا، فَإِنْ لَمْ تَسْتَطِعْ فَقَاعِدًا، فَإِنْ لَمْ تَسْتَطِعْ فَعَلَى جَنْبٍ ".
