The Book of Prayers (Kitab Al-Salat)
Muslim :: Book 4 : Hadith 1107
Abu Qatadi reported: I saw the Messenger of Allah (may peace be upon him) saying the prayer while he was carrying Umama, daughter of Zainab, daughter of the Messenger of Allah (may peace be upon him). and Abu'l-'As b. al-Rabi'. When he stood up, he took her up and when he prostrated he put her down, Yahya said: Malik replied in the affirmative.
