Birth of Imam al-Ridha (as)

Imam Ali al-Ridha, the Eighth Imam, was born in Medina in 148 Hijri and succeeded his father Imam Musa al-Kazim at age 35 after the latter's imprisonment and death by Harun al-Rashid. Facing Abbasid tyranny, he continued guiding followers discreetly. Summoned by Mamun to Merv in 200 Hijri amid succession struggles, he was appointed heir-apparent to gain Persian support, leading to Mamun's victory over Amin. Imam Ridha lived simply, established Karbala Majalis in Qom and Tus, and died poisoned in Tus in 203 Hijri at age 55, buried near Harun's tomb.

Their marriage was harmonious, focused on service to God; Fatima raised four children while performing household duties and teaching Quran. In 2 AH, Eid prayers became sunnat.

Commemoration

Imprisonment of Imam Musa al-Khadim (as)

Harun al-Rashid imprisoned Imam Musa al-Kazim due to several reasons: the Imam's high personality and recognition as the rightful Imam by Muslims, evoking Harun's envy and malice; his craving for power, fearing the Imam's superiority; inherited hatred toward Alawids; informers accusing the Imam of collecting money and seeking caliphate; the Imam's demonstrations of his closer relation to Prophet Muhammad; specifying vast borders for Fedek; and the Imam's firm, non-flattering attitude toward Harun.
