During his first term as chairman of NU, Wahid focused on reform of the "pesantren" education system and was successful in increasing the quality of "pesantren" education system so that it can match up with secular schools. In 1987, Wahid also set up study groups in Probolinggo, East Java to provide a forum for like-minded individuals within NU to discuss and provide interpretations to Muslim texts. Critics accused Wahid of wishing to replace the Arabic Muslim greeting of ""assalamualaikum"" with the secular greeting of ""selamat pagi"", which means "good morning" in Indonesian.
