[3] Yazid studied at LIPIA, then he continued his education at Imam Mohammad Ibn Saud Islamic University.

[11][12] According to his own admission, Yazid came into dispute with Jafar Umar Thalib, another Indonesian cleric, when Maluku sectarian conflict broke out in 1999.

The dispute came out because Yazid has chosen the more moderate approach and appeal to the authority under Abdurrahman Wahid, the president of Government of Indonesia to manage the conflict; whereas Jafar has chosen the radical approach by founding Laskar Jihad paramilitary armed group to intervene the Maluku conflict without permission from the government.
