حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا يَحْيَى، حَدَّثَنَا هِشَامٌ، قَالَ أَخْبَرَنِي أَبِي، عَنْ عَائِشَةَ ـ رضى الله عنها ـ أَنَّ النَّبِيَّ صلى الله عليه وسلم دَخَلَ عَلَيْهِ نَاسٌ يَعُودُونَهُ فِي مَرَضِهِ فَصَلَّى بِهِمْ جَالِسًا فَجَعَلُوا يُصَلُّونَ قِيَامًا، فَأَشَارَ إِلَيْهِمِ اجْلِسُوا، فَلَمَّا فَرَغَ قَالَ ‏ "‏ إِنَّ الإِمَامَ لَيُؤْتَمُّ بِهِ، فَإِذَا رَكَعَ فَارْكَعُوا وَإِذَا رَفَعَ فَارْفَعُوا، وَإِنْ صَلَّى جَالِسًا فَصَلُّوا جُلُوسًا ‏" ‏‏.‏ قَالَ أَبُو عَبْدِ اللَّهِ قَالَ الْحُمَيْدِيُّ هَذَا الْحَدِيثُ مَنْسُوخٌ لأَنَّ النَّبِيَّ صلى الله عليه وسلم آخِرَ مَا صَلَّى صَلَّى قَاعِدًا وَالنَّاسُ خَلْفَهُ قِيَامٌ‏.‏
