Making Dhikr collectively and reciting the entire Qur'an together in one voice
Making collective Dhikr (Remembrance of Allah), reciting the entire Qur'an together in Al-Hadrah (Sufi session of Dhikr) and reciting the entire Qur'an in one voice in the Masjids (mosques), houses, celebrations, and funerals, all have no origin in the Shari`ah. The Sahabah (Companions) (may Allah be pleased with them) were the best followers of the Shari`ah. However, it has not been reported that they did any of these things. The same applies to the pious ancestors among the early Muslim generations. In fact, all goodness lies in following the guidance of Allah's Messenger (peace be upon him). It is authentically reported that the Prophet (peace be upon him) said, (Part No. 2; Page No. 521)
Whoever does any act for which there is no sanction on our part will have it rejected.
He also said,
He who innovates things in our affairs for which there is no valid (reason) (commits sin) and these are to be rejected.
Since these practices are not authentically reported from Allah's Messenger (peace be upon him) or any of the Sahabah (may Allah be pleased with them), they are considered Bid`ahs (innovations in religion). According to the Hadith mentioned above, these practices will be rejected for their doers. Similarly, taking wages for being involved in such Bid`ahs is rejected.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
