Answered by Shaykh Amjad Rasheed
Should a ten-year old boy perform Friday prayer at the mosque, or should he pray Zuhr at home?
A boy who has turned ten may have reached puberty. If he has reached puberty, it is obligatory for him to perform the Jum’a prayer at the mosque and it is unlawful for him to leave it. If he does leave it, he will have committed a major sin.
If he has not reached puberty, he does not sin by missing the Jum’a prayer, but his guardian must order him to attend Jum’a just as he orders him to perform other prayers. The guardian is sinful if he is remiss in doing so.
