Ayatollah Sayyid Muhammad-Ridha al-Husayni al-Shirazi (Arabic: محمد رضا الحسيني الشيرازي; Persian: محمد رضا حسينى شيرازى; 1959 – June 1, 2008) was an Iraqi-Iranian Shia scholar, and the eldest son of Muhammad al-Shirazi. Mohammad Ridha Shirazi was considered to be the 'hope for the future of Islam.' The reason was mainly because of his ability to move those whose attended his lectures. It was widely understood that he would soon replace Ayatollah Sadiq al-Shirazi as Marja, and succeed as the future head of the family.
