Chapter: The permissibility of carrying children during prayer, and their garments are regarded as being pure until it is realized that they are impure. Few actions will not invalidate the prayer, and the same applies if several such actions are done but are done separately

I saw the Messenger of Allah (ﷺ) saying the prayer while he was carrying Umama, daughter of Zainab, daughter of the Messenger of Allah (ﷺ). 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.

I saw the Apostle (ﷺ) leading the people in prayer with Umima, daughter of Abu'l-'As and Zainab, daughter of the Messenger of Allah (ﷺ), on his shoulder. When he bowed, he put her down, and when he got up after prostration, he lifted her again.

I saw the Messenger of Allah (ﷺ) leading the people in prayer with Umama daughter of Abu'l-'As on his neck; and when he prostrated he put her down.

As we were sitting in the mosque, the Messenger of Allah (ﷺ) came to us, and the rest of the hadith is the same except that he made no mention that he led people in this prayer.
