Dedication

I submit this humble effort to the great position of the pioneer of the intellectual and cognitive renaissance in Islam, the Prophet’s descendant, Imam Ja‘far al-Sa’diq, peace be on him. I have made this research about his grandson Imam ‘Ali b. Musa’ al-Ridha’, peace be on him, while hoping that he will kindly accept, so it would be a treasure for me on the Day of Resurrection.
