It was narrated from 'Amr bin Sulaim Az-Zuraqi that he heard Abu Qatadah say:

"While we were sitting in the Masjid. The Messenger of Allah ﷺ came out to us carrying Umamah bint Abi Al-'As bin Ar-Rabi', whose mother was Zainab, the daughter of the Messenger of Allah ﷺ. She was a little girl and he was carrying her. The Messenger of Allah ﷺ prayed with her on his shoulder, putting her down when he bowed and picking her up again when he stood up, until he completed his prayer."

أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا اللَّيْثُ، عَنْ سَعِيدِ بْنِ أَبِي سَعِيدٍ، عَنْ عَمْرِو بْنِ سُلَيْمٍ الزُّرَقِيِّ، أَنَّهُ سَمِعَ أَبَا قَتَادَةَ، يَقُولُ بَيْنَا نَحْنُ جُلُوسٌ فِي الْمَسْجِدِ إِذْ خَرَجَ عَلَيْنَا رَسُولُ اللَّهِ ﷺ يَحْمِلُ أُمَامَةَ بِنْتَ أَبِي الْعَاصِ بْنِ الرَّبِيعِ وَأُمُّهَا زَيْنَبُ بِنْتُ رَسُولِ اللَّهِ ﷺ وَهِيَ صَبِيَّةٌ يَحْمِلُهَا فَصَلَّى رَسُولُ اللَّهِ ﷺ وَهِيَ عَلَى عَاتِقِهِ يَضَعُهَا إِذَا رَكَعَ وَيُعِيدُهَا إِذَا قَامَ حَتَّى قَضَى صَلاَتَهُ يَفْعَلُ ذَلِكَ بِهَا .
