باب كَيْفَ يَفْعَلُ إِذَا افْتَتَحَ الصَّلاَةَ قَائِمًا وَذِكْرِ اخْتِلاَفِ النَّاقِلِينَ عَنْ عَائِشَةَ فِي ذَلِكَ

It was narrated hat Aishah said:
"The Messenger of Allah (ﷺ) used to pray standing and sitting. If he started to pray standing, he would bow standing and if he started to pray sitting, he would bow sitting."
أَخْبَرَنَا عَبْدَةُ بْنُ عَبْدِ الرَّحِيمِ، قَالَ أَنْبَأَنَا وَكِيعٌ، قَالَ حَدَّثَنِي يَزِيدُ بْنُ إِبْرَاهِيمَ، عَنِ ابْنِ سِيرِينَ، عَنْ عَبْدِ اللَّهِ بْنِ شَقِيقٍ، عَنْ عَائِشَةَ، قَالَتْ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يُصَلِّي قَائِمًا وَقَاعِدًا فَإِذَا افْتَتَحَ الصَّلاَةَ قَائِمًا رَكَعَ قَائِمًا وَإِذَا افْتَتَحَ الصَّلاَةَ قَاعِدًا رَكَعَ قَاعِدًا ‏.‏
