Musnad Ahmad 1007:63

'Abd al-Rahman and 'Abd al-Razzaq narrated to us, they said: Malik narrated to us, from 'Amir ibn 'Abd Allah, from 'Amr ibn Sulaym, from Abu Qatadah, he said: 'Abd al-Razzaq said in his narration: I heard Abu Qatadah say: I saw the Messenger of Allah, may Allah bless him and grant him peace, while he was carrying Umamah, the daughter of Zaynab. 'Abd al-Razzaq said: Upon his shoulder. When he bowed and prostrated, he would put her down, and when he stood up, he would carry her.
