After his father's death, Abu-l-Hasan inherits substantial wealth but, weary of insincere friends, decides to host lavish gatherings for strangers only, entertaining them with music and dancing. One evening, he expresses a desire to experience the Caliph's power for a day. Harun al-Rashid, intrigued by this wish, orchestrates a plan: he invites Abu-l-Hasan to the palace, serves him a drugged drink, and upon his awakening, convinces him that he is the Caliph. Abu-l-Hasan enjoys this illusion of authority until the ruse is revealed, leading to a mix of confusion and amusement.
