Madhhab (Arabic: مذهب‎ maḏhab, IPA: [ˈmæðhæb], "doctrine"; pl. مذاهب maḏāhib, [mæˈðæːhɪb]; Turkish: mezhep; transliterated Urdu: mazhab or mezheb) is a Muslim school of law or fiqh (religious jurisprudence). In the first 150 years of Islam, there were many such "schools". In fact, several of the Sahābah, or contemporary "companions" of Muhammad, are credited with founding their own. The prominent Islamic jurisprudence schools of Damascus in Syria (often named Awza'iyya), Kufa and Basra in Iraq, and Medina in Arabia survived as the Maliki madhhab, while the other Iraqi schools were consolidated into the Hanafi madhhab. The Shafi'i, Hanbali, Zahiri and Jariri schools were established later, though the latter school eventually died out.

It is claimed that the schools of thought were developed in the 9th and 10th centuries as a means of excluding dogmatic theologians, government officials and non-Sunni sects from religious discourse. Historians have differed regarding the time at which each of the various schools had emerged. It is said that Sunni Islam was initially split into six schools (Maliki, Hanafi, Shafi'i, Hanbali, Zahiri, Jariri) before various ruling dynasties later narrowed the number down to four, with the Mamluk Sultanate in Egypt eventually creating four independent judicial positions, thus solidifying the Maliki, Hanafi, Shafi'i and Hanbali schools. Conversely, some view that Sunni jurisprudence falls into two groups: Ahl al-Ra'i, or people of opinions, due to their emphasis on scholarly judgment and reason; and Ahl al-Hadith, or people of traditions, due to their emphasis on restricting juristic thought to only what is found in scripture.

He is the founder and president of the Islamic Research Foundation (IRF), a non-profit organisation that owns the Peace TV channel based in Dubai, UAE. He is sometimes referred to as a televangelist. Before becoming a public speaker, he trained as a doctor. He has written two booklets on Islam and comparative religion. He is regarded as an exponent of the Salafi ideology; he places a strong emphasis on individual scholarship and the rejection of "blind Taqlid", which has led him to repudiate the relevance of sectarian or Madh'hab designations, all the while reaffirming their importance.

Later he enrolled at Kishinchand Chellaram College, before studying medicine at Topiwala National Medical College and Nair Hospital and later the University of Mumbai, where he obtained a Bachelor of Medicine and Surgery (MBBS).
