Sahih al-Bukhari, Prayers (Salat)

Book 8, Hadith 163

Narrated ‘Abu Qatada Al-Ansari:

Allah’s Messenger was praying and he was carrying Umama the daughters of Zainab, the daughter of Allah’s Messenger and she was the daughter of ‘As bin Rabi`a bin `Abd Shams. When he prostrated, he put her down and when he stood, he carried her (on his neck).
