What is the ruling regarding children who are not yet accountable (mukallaf), or those about whom it is unknown whether they are accountable for prayer or other acts of worship? And is this obligatory upon someone other than the guardian, whether the guardian is present or absent?

The guardian of a child must command him to perform acts of worship so that he may become accustomed to them and find them easy. Scholars have unanimously agreed that acts of worship are not obligatory until puberty, but they have recommended training children in them in hopes of their blessings for them.

Every responsible person must command those who obey him to pray, even children. Whoever does not command a child to pray will be punished, and the adult will be severely disciplined for it, because he has disobeyed Allah and His Messenger.

The child is rewarded for his prayers, fasting, Hajj, and other deeds, and is preferred thereby over one who has not performed such deeds. If there is doubt about a child's puberty, he falls under the ruling of a child, because the default is non-puberty until it is proven with certainty.

Some scholars have explicitly stated that the command to the child to pray includes others besides the guardian, whether the guardian is present or not.
