His public exegesis of the Qur’an, delivered in Hausa every year during the month of Ramadan, attracts thousands. Additionally, millions of West Africans listen to it on the radio or buy recordings. He has critically engaged with puritanical Islamic schools of thought since the early 1980s. In July 2014, he escaped a suicide bombing attack which killed 23 people.
