Is it permissible for a boy to lead the prayer?

Question:
His Eminence the Honored Shaykh: Abdul Aziz ibn Baz
Peace be upon you, and Allah's mercy and blessings, and may you be well every year.
I ask your Eminence: Is it permissible for a boy to lead the prayer? May Allah reward you with good for enlightening the Muslim community.

Answer:
And upon you be peace, and Allah’s mercy and blessings, after that:
There is nothing wrong with a boy leading the prayer if he has completed seven years of age or more and he knows how to perform the prayer correctly, because it is established from the Prophet (peace and blessings be upon him) what indicates this. However, it is better to choose the one who is most proficient in recitation from the congregation. If they are equal in recitation, then the one most knowledgeable of the Sunnah. If they are equal in the Sunnah, then the one who migrated earliest. If they are equal in migration, then the oldest in age, as this is authentically reported from the Prophet (peace and blessings be upon him).
And peace be upon you and the mercy of Allah and His blessings.
