The Robe
Interpreters mentioned that seeing a robe made of silk (khazz), qaz, or brocade might indicate that the dreamer will gain authority or a position of power, and their status will be proportional to the robe's strength and quality. However, wearing these types of robes might be disliked in religion unless it is during war.
