Since then, Yafie taught at various Islamic higher educational institutions in Jakarta, and became increasingly active in MUI. At the same time, he was re-elected as an executive at the 1979 NU conference in Semarang and 1984 conference in Situbondo, and in the 1989 conference in Krapyak as the representative of the chairman. Because Ahmad Siddiq, the incumbent chairman of the advisory board, died in 1991, he acted as the deputy chairman of the advisory board temporarily until 1992. After having disputes with Abdurrahman Wahid regarding the issues of aid from the Foundation for Social Welfare Fund, Yafie withdrew from NU chairmanship in 1992, making him, so far, only Chairman of NU that did it.
