All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah and that Muhammad is His Slave and Messenger as well as that of his family and all his companions.
According to the most preponderant opinion of the scholars it is permissible to recite the Quran or perform any other act of worship and intend its reward for the dead. However, there is no evidence on doing this in a group.
Allaah Knows best.
