6.5.5. Standing Together for Prayer
Sometimes it is appropriate that a group of people should stand up for praying together, and it is much better if the number of people be at least forty, or at least four people each of them repeating his wants ten times, or in case there is only one person, it would be much better if he asks for his wants forty times.
 Group-prayer may seems in contradiction with whatever has been explained earlier about praying in secrecy. Some of the prayers and wants require isolation and privacy and for them congregation and assembly might be harmful, but on the other hand prayers for asking immunity from common disasters should be offered in a group as congregation prayers [Author].
