We Shias have the utmost respect for pious companions who obeyed the Prophet (s) and remained steadfast on the Prophet’s path. And we are critical of those Sahaba who were either hypocrites or they disobeyed the Prophet.
Historical sources indicate that Abdurrahman son of Abu Bakr vehemently opposed Muawiyah and Yazid for their injustices, and we Shias respect that about him. He did not pledge them allegiance. However, we have more respect for his brother Mohammad because Mohammad was very loyal to the Prophet’s family and Imam Ali praised him a lot.
