Praise be to Allah.
The question is somewhat vague. If what is meant is that they recite it all together, in unison, pausing and stopping at the same time, then this is not prescribed in Islam and at the very least it is makrooh (disliked), because it is not reported that the Prophet (peace and blessings of Allaah be upon him) or his Companions (may Allaah be pleased with them) did any such thing. But if this is done for the purpose of teaching, we hope that there is nothing wrong with it. If what is meant is that the people gather to recite Qur’aan in order to memorize and learn it, and each one recites whilst the others listen, or each one reads to himself – not in unison with the others – then this is permissible because it was reported that the Messenger of Allaah (peace and blessings of Allaah be upon him) said: “No group of people gathers in one of the houses of Allaah to recite the Book of Allaah and study it together, but tranquillity descends upon them, the angels surround them, mercy comes down upon them, and Allaah mentions them to those who are with Him.”(Reported by Muslim).
