There are four major schools of worship in Islam, also known as the Sunni schools of thought or Madhhabs. These are the Hanafi, Maliki, Shafi'i and Hanbali schools. These schools of thought have developed over time and are based on the interpretation of the Quran, Hadith and Islamic jurisprudence by the scholars. While there are differences in their opinions and interpretations, they all share the same fundamental beliefs and principles of Islam. Additionally, there is also the Shia school of thought, which differs from the Sunni schools in some theological beliefs and practices.
