We were sitting in the mosque when the Messenger of Allah ﷺ came upon us carrying Umamah daughter of Abul'As ibn ar-Rabi'. Her mother was Zaynab daughter of the Messenger of Allah ﷺ. She (Umamah) was a child and he (the Prophet) was carrying her on his shoulder. The Messenger of Allah ﷺ led (the people) in prayer while she was on his shoulder. When he bowed he put her down and took her up when he got up. He kept on doing so until he finished his prayer. (Using translation from Abū Dāʾūd 918)   

أَنَّهُ سَمِعَ أَبَا قَتَادَةَ يَقُولُ بَيْنَا نَحْنُ فِي الْمَسْجِدِ جُلُوسٌ خَرَجَ عَلَيْنَا رَسُولُ اللهِ ﷺ يَحْمِلُ أُمَامَةَ بِنْتَ أَبِي الْعَاصِ بْنِ الرَّبِيعِ وَأُمُّهَا زَيْنَبُ بِنْتُ رَسُولِ اللهِ ﷺ وَهِيَ صَبِيَّةٌ يَحْمِلُهَا عَلَى عَاتِقِهِ فَصَلَّى رَسُولُ اللهِ ﷺ وَهِيَ عَلَى عَاتِقِهِ يَضَعُهَا إِذَا رَكَعَ وَيُعِيدُهَا إِذَا قَامَ حَتَّى قَضَى صَلَاتَهُ يَفْعَلُ ذَلِكَ بِهَا
