History of Birthday of Prophet and Imam Sadiq
Iran’s official Shi'a calendar marks the seventeenth of Rabi al-Awwal as the birthday of Prophet Muhammad and of Imam Jafar al-Sadiq. The shared anniversary turns a devotional celebration of the Prophet’s life into a day that also honours a major Shi'a teacher and jurist.
Mosques, schools and homes may host recitation, praise poetry, talks and shared food. It is a celebratory public holiday, distinct from the mourning dates elsewhere in the lunar calendar. The Gregorian date moves each year and needs annual official confirmation.
Iran follows the seventeenth of Rabi al-Awwal for Muhammad’s birthday, while many Sunni communities use the twelfth. The interval is officially promoted in Iran as Islamic Unity Week, creating space for conferences and inter-Muslim messaging alongside popular celebration. Pairing the Prophet with Imam Jafar al-Sadiq gives the day a specifically Twelver Shi'a character.
