Do Muslims have many sects?

Muslims have no sects. In Islam, there are two major schools of thought, the Shia and the Sunni. Both have many things in common. They follow the same book - Quran. They follow the same prophet Muhammad (P). Both offer their prayers five time a day. Both fast in the month of Ramadan. They both go for hajj, pilgrimage to Mecca. Those who follow Prophet Muhammad (P), in accordance with his sayings and actions, are called Sunni and those who in addition follow the sayings and views of Ali (Muhammad's son-in- law), as the rightful successor to Prophet Muhammad (P), are called Shia. Shia means a partisan (party of Ali) and it started more as a political party to help Ali in his conflict with his political adversaries. Most Shias live in Iran and Iraq while the rest of the Muslim world is mostly Sunni. Shias comprise about 16-percent of the Muslim population.

shias are kaafir, islaam is free of them.
