Just like Christianity, Islam has been shattered into numerous sects, even tough the essential religion is the same, ie worship ONE God, Allah, and serve humanity based on the examples of the prophets and messengers, specifically on the example of the Last Messenger, Prophet Muhammad (SWAS). Scholars of Islamic Studies, consider two main branches of Islam, Sunni Islam and Shiite Islam.
In a nutshell, Sunni Islam is all about its followers following the best practices (natural principles) that Prophet Muhammad (SWAS) was inspired to live by through continuous insights from God (Allah) while Shiite Islam considers that a person can be righteous if they take the family of the Prophet (SWAS) and his biological descendents as their religious leaders (imams). Whereas, Sunni Islam is all about learning and following the Prophetic Sunnah (his life pattern based on natural principles) as they were taught by him to his companions, the Sahaba (RA), some of whom Shiite scholas consider usurper of the Islamic State after the demise of the Prophet (SWAS).
As modern challenges whether they be mental health or AI ethics, can better be addressed by Sunni Islam using its methodology of insights from natural principles (the Sunnah), which can be applied to understand any phenomenon. Whereas Shiite Islam tends to relegate understanding to its religious leaders, in general. Thus, the ideal Shiite Islamic State is that led by their Shiite scholars, with the general population seldom questioning as fervent followers, in general. In contrast, the Caliph of the ideal Sunni Islamic state is equal to the general population and can be questioned by anyone, in general.
Whatever, the modern challenge, the common Sunni Muslim is able to "understand" it better from a more personal holistic religious way than a common Shiite Muslim, in general, as the former is suppose to develop a life full of divine insights using the example (Sunnah) of the Prophet (SWAS). In contrast, the common Shiite Muslim is suppose to obey their spiritual leaders (imams), perhaps "blindly".
