The 28th day of the month of Safar (the second month in the lunar calendar) marks the demise of the Prophet Mohammed (PBUH). The day also marks the martyrdom of the holy prophet’s grandson Imam Hassan (PBUH), the second revered Shiite imam.
Nationwide mourning ceremonies are also being held to mark the tragic events on Sunday.
Prophet Mohammed (PBUH) was born in about 570 AD in the Saudi Arabian city of Mecca. He became the final prophet by God at the age of 40. He passed away at the age of 63 after disseminating the message of Islam for 23 years.
Imam Reza (PBUH), the eighth Imam of Shiites, who was martyred on the last day of the month of Safar, will be honored held in Iran on December 23.
