evidence: The Jamkaran Mosque (Persian: مسجد جمکران; Masjed-e Jamkarân) is one of the primary significant mosques in Jamkaran, a village in the outskirts of the city of Qom, Iran. The mosque, six kilometers east of Qom, has long been a sacred place, at least since 373 A.H., 17th of Ramadan (22 February 984 C.E.), when according to the mosque website, one Sheikh Hassan ibn Muthlih Jamkarani is reported to have met the 12th Imam along with the prophet Al-Khidr. Jamkarani was instructed that the land they were on was "noble" and that the owner — Hasan bin Muslim — was to cease cultivating it and finance the building of a mosque on it from the earnings he had accumulated from farming the land.[1][2] [...] On 4 January 2020, a blood-red flag symbolizing vengeance unfurled above the dome in response to the 2020 Baghdad International Airport airstrike. However, usually the red flag is raised during Muharram and it also flown in response to the COVID-19 pandemic in Iran whenever a milestone of casualties was reached.[6]
