About Qom Qom is considered holy by Shi`a Islam, as it is the site of the shrine of Fatema Mæ'sume, sister of Imam `Ali ibn Musa Rida (Persian Imam Reza, 789–816 AD). The city is the largest center for Shi'a scholarship in the world, and is a significant destination of pilgrimage. Qom is famous for a brittle toffee called "Souhan" , considered a souvenir of the city and sold by 2000 to 2500 "Souhan" shops. Qom has developed into a lively industrial centre owing in part to its proximity to Tehran. It is a regional centre for the distribution of petroleum and petroleum products, and a natural gas pipeline from Bandar Anzali and Tehran and a crude-oil pipeline from Tehran run through Qom to the Abadan refinery on the Persian Gulf. Qom gained additional prosperity when oil fields were discovered at Sarajeh near the city in 1956 and a large refinery was built between Qom and Tehran.
