Yahya related to me from Malik from Amir ibn Abdullah ibn az- Zubayr from Amr ibn Sulaym az-Zuraqi from Abu Qutada al-Ansari that the Messenger of Allah ﷺ used to pray carrying Umama, who was the daughter of his daughter Zaynab by Abu'l As ibn Rabia ibn Abd Shams. When he prostrated, he put her down, and when he got up he carried her.
أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ يُصَلِّي وَهُوَ حَامِلٌ أُمَامَةَ بِنْتَ زَيْنَبَ بِنْتِ رَسُولِ اللَّهِ ﷺ وَلأَبِي الْعَاصِ بْنِ رَبِيعَةَ بْنِ عَبْدِ شَمْسٍ فَإِذَا سَجَدَ وَضَعَهَا وَإِذَا قَامَ حَمَلَهَا
