Joining Qur'an khatam groups
Q: Recently few messages have been going around regarding Quran Khatam groups and its authentication, I would like to know if:
1. Is it permissible to join a quran khatam group?
2. Is it permissible to have time limits to complete the khatam?
3. Can you join the group with the intention of making sure that you are completing at least 1 para a week even if the group was created with the intention of esaale sawaab of marhoomeen?
