Final answer:
The majority of Muslims in Pakistan are Sunni, making up about 85% of the Muslim population, while Shia Muslims represent roughly 15%.
Step-by-step explanation:
The majority of Muslims in Pakistan follow Sunni Islam. About 85% of the Muslim population in Pakistan is Sunni, and approximately 15% is Shia. Sunni Muslims look to the family and community for direction and believe that any pious man following the example of Muhammad could lead the community. Conversely, Shia Muslims consider Muhammad's son-in-law Ali as the originator of a direct line of divinely chosen leaders, known as Imams. Other minor Islamic sects exist, such as Sufism and the Ahmadiyya, but they comprise a smaller percentage of the Muslim population.
