This is a painting of mostly bearded men in a mosque. (Source: https://www.amazon.fr/Gulistan-Contes-persans-Reza-Dalvand/dp/2352901766) If the shape of their mouths is to be relied on, they appear to be talking, singing or chanting. Some on the upper floor may be discussing, according to their arm-waving. One is up in the minaret perhaps on his way to the top, possibly indicating the moment before the call to prayer. Why is a man in the foreground touching the only beardless one? Is this a depiction of some kind of youth initiation ritual (hence the beardlessness)? or teaching singing/chanting by drawing attention to vibrations in the abdomen? If not, what is going on?
EDIT: The image is a recent illustration by Reza Dalvand from the cited book, although it might have been modeled after older art. I received the image by email and was hasty to post it here without enquiring about the source first. I am not sure if my question is still valid.
EDIT 2: The young man has just been admitted as a sage by 10 other sages (counting out the minaret man). He is replying to his father that he would rather remain silent about it than risk saying anything stupid. This does not explain the body language however.
