Over one million Iranian pilgrims have returned home following this year’s Arbaeen pilgrimage, according to officials. The pilgrims re-entered the country through border crossings in the southwestern province of Khuzestan. This information was released by the head of Khuzestan’s Migration and Passport Police on Friday. Arbaeen marks the 40th day after the martyrdom of Imam Hussein, the grandson of Prophet Muhammad, and is a significant religious observance for Shia Muslims. The annual pilgrimage attracts millions of devotees to Karbala, Iraq. Authorities prepared for a large influx of returnees and facilitated their entry into Iran. The province saw a substantial movement of people completing their religious journey.
