Is it permissible to delay a boy who is advanced for the first row in prayer so that an adult man may pray in his place?

The Prophet, peace and blessings be upon him, commanded those of understanding and maturity to come forward for prayer. This was not a prohibition for others. So, whoever arrives first at the first row or behind the Imam has a greater right to that spot, even if they are young. It is not permissible to remove children if they precede adults to the first row, and delaying them discourages them from prayer. If a child comes forward to a place, he has a greater right to it. It is permissible for children to be in the row, even if they are directly behind the Imam, and no one is allowed to remove them.
