Imaam Muhammad Nasir ud-Deen al-Albani (1914–1999) was a renowned Islamic scholar known for his work in Hadith authentication, belief (aqeedah), and da’wah methodology. His writings emphasize a return to authentic Islamic sources — Qur’an and Sunnah — and clarification of core concepts such as Tawheed, often countering misunderstood or mixed methodologies in contemporary discourse.
