By the late 1960s, after the death of Bello, Gumi's major Nigerian political support and moderating influence was gone. He felt the new administration had the political power to curtail his views, and in the process, he resorted to consulting his friends in
Saudi Arabia for moral, dogmatic and financial support to promote a
Wahabbist interpretation of Islam centering on the rejection of mysticism, return to
puritanical Islamic teaching, and rejection of the then dominant Sufi brotherhoods. He also wanted to find mass support in his battle with the brotherhoods and what he felt was their hold on the political process. Gumi became more interested in ensuring political support for his ideas, based on his perception that a political Muslim has the power to change the course of lives of a larger number of people than publishing scholarly works or engaging in private debates and gradually became more interested in political means to achieve an Islamic reformist end. In the process, he became a supporter of
women's rights to vote. By the early 1970s, he wished to contest what he felt was the hijacking of major Islamic political organizations by the Fityan al-Islam, an organization founded in Kano by Mudi Salga, a leader of the Salgawa network, who was opposed to some of the policies of the late
Ahmadu Bello and his
Jamaat Nasr al-Islam (the Association for the Support of Islam). He decided to start a movement and relied on his old students to spread his views on Islamic dogma, prodding many to take jobs at the JNI and enter into legislative duties. He used one of his students, Sheikh Ismaila Idris Ibn Zakariyya, as a founder for the new movement to challenge the Sufi brotherhoods and ensure a return of Islam to a fundamental way. The rise of this movement ''
Izalatul Bidi'a Wa Ikamatul Sunnah or Movement for the Demolition of
Bid'ah and Revival of the Sunnah'', popularly called Izala, heralded the
radicalization of Northern Nigeria. Many within the political cycles and Sufi Brotherhoods of
Northern Nigeria held that Gumi was the principal who drove a wedge between Muslims and non-Muslims in Northern Nigeria; that his interpretations of the
Hadith and Qur'an were based on his own personal views and not the Sunnah; and that he was monopolizing the
mass media for his personal views. He was also criticized for his rebellious views on traditional authorities. Gumi believed that Nigerian Muslims should never accept a non-Muslim ruler, but he also advocated peaceful coexistence with non-Muslim groups. ==Awards and honors==
