"The Messenger of Allah (ﷺ) was ill, and we prayed behind him while he was sitting, and Abu Bakr repeated his takbirs so that the people could hear them. He turned to us and saw us standing, so he gestured to us to sit down. So we prayed behind him sitting. When he said the salam he said: 'Just now you were doing what the Persians and Romans do for their kings when they are sitting. Do not do that. Follow your Imams: If they pray standing then pray standing, and if they pray sitting then pray sitting.'"
"I saw the Messenger of Allah (ﷺ) leading the people in prayer, carrying Umamah bint Abi Al-'As on his shoulder. When he bowed he put her down and when he finished prostrating he picked her up again."
أَخْبَرَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، قَالَ حَدَّثَنَا حَاتِمُ بْنُ وَرْدَانَ، قَالَ حَدَّثَنَا بُرْدُ بْنُ سِنَانَ أَبُو الْعَلاَءِ، عَنِ الزُّهْرِيِّ، عَنْ عُرْوَةَ، عَنْ عَائِشَةَ، - رضى الله عنها - قَالَتِ اسْتَفْتَحْتُ الْبَابَ وَرَسُولُ اللَّهِ صلى الله عليه وسلم يُصَلِّي تَطَوُّعًا وَالْبَابُ عَلَى الْقِبْلَةِ فَمَشَى عَنْ يَمِينِهِ أَوْ عَنْ يَسَارِهِ فَفَتَحَ الْبَابَ ثُمَّ رَجَعَ إِلَى مُصَلاَّهُ .
"I knocked at the door when the Messenger of Allah (ﷺ) was offering a voluntary prayer. The door was in the direction of the Qiblah so he took a few steps to his right or left and opened the door, then he went back to where he was praying."
