Answered by Sayyidi Habib Umar bin Hafiz (may Allah protect him and benefit us by him)
We have a weekly gathering in which we read adhkar of the Ba `Alawi Tariqah. Is it fine for people who are not connected to the Tariqah to attend?
It is fine for everyone who loves good and everyone who wishes to benefit to attend. Attending these gatherings is not restricted to those who have entered this Tariqah. One of the objectives of the Tariqah is benefiting people. Even non-Muslims may attend if it is likely that they will benefit as long as they do not show bad etiquette and do not cause people to have doubts.
Those who should not attend are those who criticise or have doubts about what is taking place in the gathering. This is to protect them from becoming confused and from committing a wrongdoing by condemning the people in the gathering. It is also to protect the people that attend the gathering from becoming confused and thus not attending.
