Is it permissible to bring a ping-pong table and other means of entertainment into the mosque at Dar Al-Quran if there is sufficient space for that?

If the Quranic House (Dar al-Quran) is located inside the mosque, then playing tennis or other games within it is not permissible. However, if it is located outside the mosque, there is no objection to that, provided that the playing adheres to the Sharia regulations and does not disturb those who are reciting.
