A glance at the Biography of Imam Reza

A glance at the Biography of Imam Reza A. S
Imam Reza (A.S.), the eighth Shi'ite Imam was born on Thursday 11th Zee al-Qa'adah 148 A.H. in Medina. The new-born child was named Ali by his holy father, Imam Musa al-Kazim (A.S.), the seventh Shi'ite Imam. He was divinely entitled al-Reza and his nickname was Abul Hasan.

For many times Imam Musa Al-Kazem (A.S) explicitly introduced his eldest son "Ali" as his immediate successor to accede to the divine position of Imamate.
Subsequent to the martyrdom of his father in Baghdad, on the 25th of Rajab 183 A.H. / 1 September, 799 A. D. in the prison of Abbasid caliph, Harunal_rashid, he attained the holy position of Imamate, when he was thirty five years old, and he held that divine position for twenty years.
Three Abbasid caliphs were his contemporaries: for the first ten years Harun al- Rashid, for next five years Amin and finally for the last five years Ma'mun.
