He would likewise step up and down the pulpit during the prayer so they could observe how he prayed, and he once opened the door for ʿĀʾishah while still praying—along with other actions that do not disrupt the prayer. From this we learn that a slight movement undertaken for a need is permissible.

Points derived from the hadith

1. Such minor movement is allowed in both obligatory and voluntary prayers, whether one is leading, following, or praying alone, even when there is no pressing necessity. This is the view of the verifying scholars.

2. It is permissible to touch or carry someone whose impurity is only suspected, because the default ruling is purity, which overrides mere conjecture. In this context the suspicion concerns the clothes or bodies of small children.

3. The hadith highlights the Prophet’s ﷺ humility, refined character, and mercy.

Benefit
Based on extensive survey of the evidences, some scholars have divided movement during prayer into four categories:

1. Forbidden and invalidating: extensive, continuous movement undertaken without necessity and unrelated to the interests of the prayer.

2. Disliked yet not invalidating: slight, unnecessary movement that brings no benefit to the prayer, such as casually fiddling with one’s clothing or body. It undermines the required humility, and there is no need for it.

3. Permissible: slight movement undertaken for a need. This appears to be the category to which the Prophet’s ﷺ actions belong—carrying the child, ascending and descending the pulpit during prayer, opening the door for ʿĀʾishah, and similar acts performed either out of need or to illustrate what is allowed.

4. Legislated: movement that directly serves the interests of the prayer—such as stepping forward to a more virtuous spot or closing a gap in the rows—or that fulfills a praiseworthy, commanded action, like the forward and backward movements prescribed in the prayer of fear or those required in an emergency to rescue someone from danger.
