If a small girl is carried on one's neck during the Salat (prayer)

Narrated Abu Qatada Al-Ansari: Allah's Messenger (ﷺ) was praying and he was carrying Umama the daughters of Zainab, the daughter of Allah's Messenger (ﷺ) 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).
