Sunan an-Nasa'i, Volume 2, Book 13, Hadith 1205 (DarusSalam) ⓘ
It was narrated from Abu Qatadah that: The Messenger of Allah used to pray carrying Umamah. When he prostrated he put her down and when he stood up he picked her up again.
أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا مَالِكٌ، عَنْ عَامِرِ بْنِ عَبْدِ اللَّهِ بْنِ الزُّبَيْرِ، عَنْ عَمْرِو بْنِ سُلَيْمٍ، عَنْ أَبِي قَتَادَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كَانَ يُصَلِّي وَهُوَ حَامِلٌ أُمَامَةَ فَإِذَا سَجَدَ وَضَعَهَا وَإِذَا قَامَ رَفَعَهَا .
