He made the decision just three after days after recommending the expulsion of a student for making anti-Islamic remarks.
A Facebook post of Saifullah Al-Hadi, a third-year student of his department, went viral on Friday. Saifullah made derogatory remarks about Makkah and Zamzam Well in his post.
Meanwhile, the university's acting registrar SM Abdul Latif said Arabic language and literature department chairman Moshtaq Mohammad Abdul Moktader Munwar Ali submitted a resignation letter to him showing personal reasons.
But many Islamic University teachers and students said a vested quarter might have threatened Munwar Ali for recommending the permanent expulsion of the student.
However, the academic said the key reason behind his resignation was family issues. "I did not receive any threat."
