The name of the mosque is derived from the emperor's respect for the great scholar and father-in-law from Lebanon, the emperor built the mosque for him to lecture and worship. It is the best and most brilliant manifestation of Persian Islamic civilization. Standing under the dome feels very shocking, the details of the pattern are amazing, and the light is even more beautiful in the morning and evening. Tickets 200,000 riyals.
