Narrated AbuQatadah: 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
