Carrying small children and putting them down while praying
أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا سُفْيَانُ، عَنْ عُثْمَانَ بْنِ أَبِي سُلَيْمَانَ، عَنْ عَامِرِ بْنِ عَبْدِ اللَّهِ بْنِ الزُّبَيْرِ، عَنْ عَمْرِو بْنِ سُلَيْمٍ، عَنْ أَبِي قَتَادَةَ، قَالَ رَأَيْتُ النَّبِيَّ صلى الله عليه وسلم يَؤُمُّ النَّاسَ وَهُوَ حَامِلٌ أُمَامَةَ بِنْتَ أَبِي الْعَاصِ عَلَى عَاتِقِهِ فَإِذَا رَكَعَ وَضَعَهَا فَإِذَا فَرَغَ مِنْ سُجُودِهِ أَعَادَهَا .
It was narrated that Abu Qatadah said: "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."
