Al-Sayyid al-Shaykh MUHAMMAD HISHAM KABBANI comes from a well-respected Lebanese family of Muslim scholars, jurists, muftis, and teachers, whose prominence in the Middle East goes back to the early centuries of Islam. Shaykh Hisham is vice-chairman of Al-Sunna Foundation of America (ASFA) and presently the most famous Muslim da`i and scholar in the Americas. He has lectured in the Middle East, Far East, Africa, and Europe on Islam in the modern world, Islamic education, and spirituality. He came to America eight years ago on the orders of his shaykh, Mawlana Muhammad Nazim Adil al­Haqqani, mufti of Cyprus and world head of the Naqshbandi Tariqa, with the directive to spread Islam among non­Muslims. He has since helped establish more than thirty mosques and Islamic centers and has conveyed the Message of Islam to countless people, by Allah's grace. He authored several books on Islam and Sufism, and frequently lectures at centers of religious learning and universities. His most recent work are a three-volume, 1,500-page refutation of "Salafi" dogmas, entitled Islamic Beliefs and Doctrine According to Ahl al-Sunna: A Repudiation of "Salafi" Innovations, as well as its summarized version entitled al-Radd al-qati` `ala al-salafi al-da'i` (The Decisive Answer to the Lost "Salafi"). The present work is a response to the growing campaign of "Salafi" disinformation on tasawwuf. It is hoped the reader will find in these works an effective antidote against the diseases of alteration, modernization, and anti-spirituality that are presently poisening the core and kernel of our Deen.
