The samā or sema is usually led by a who is the spiritual leader of the ceremony.

I believe the answer is: Sheik

The main role of sheik is to open and close the ceromny with the Recitation of the Quran. In the middle of the ceremony, they also conducted preaching which is similar to what the priests are doing in christian church.

They tend to only acknowledge someone as a legitimate sheik if that person is considered to be much more experienced in mythical/spiritual journey compared to other members.

I personally think St. Patrick's Day.

Explanation:

I mean think of it, what do you really do on that day except pinch people who don't wear green, and mention things that relate to leprechauns all day!
