Grand Ayatollah Sayyid Abd al-A'la Musawi Sabziwari (Persian: عبدالاعلی موسوی سبزواری; Arabic: عبد الأعلى الموسوي السبزواري; December 21, 1910 – August 16, 1993) was an Iranian Shia marja'.

[1][2][3][4][5] He is regarded as one of the most influential grand religious authorities and he was a contemporary of Abu al-Qasim Khoei.

Sabziwari's great ancestor was Ibrahim al-Mujab, the grandson of the seventh Shia Imam, Musa al-Kadhim.

[11] In 1924, he travelled to Mashhad and studied under senior clerics such as Sheikh Hasanali Isfahani, Mirza Adib Nishaburi, Mirza Askar Shahidi, Sayyid Muhammad Lawasani Assar and Sheikh Ali Akbar Nahawandi.

[12] In Najaf, he attended the classes run by great religious authorities such as Sheikh Muhammad-Hussain Na'ini, Shiekh Dhiya al-Dina Iraqi, Sheikh Muhammad-Hussain al-Gharawi Isfahani and Sayyid Abu al-Hasan sfahani.

[13] He arranged to be taught by Sheikh Muhammad-Jawad Balaghi a year before he passed away, and participated in his Quranic exegesis classes.

According to London-based researcher, Dr. Sahib al-Hakim, Sabziwari was killed by poisoning at the hands of Bathist regime operatives.
