2. Dislike of other companions
Due to their belief in the Imams’ right to succession, Shias naturally dislike or feel averse to other caliphs who ruled instead, such as Abu Bakr, the immediate successor to the Prophet, and the two caliphs who followed him, Umar and Usman. They thus also refuse to formulate their religious law on the ahadeeth and traditions narrated by these companions, leading to the visible differences in practice that separate the two sects. Sunnis, however, treat these men with the utmost respect which they believe is deserving of their close companionship with the Prophet.
