Musannaf Ibn Abi Shaybah

Hazrat Usman performed four rak‘ahs in Mina. Hazrat Abdullah states that I performed two rak‘ahs in Mina with the Noble Prophet (peace and blessings be upon him), and I also performed two rak‘ahs with the two Shaykhs. Then the people’s ways became separate and distinct, so I wished to perform four rak‘ahs instead of two. Hazrat A‘mash states that Hazrat Mu‘awiyah bin Qurrah narrated to me that after that, Hazrat Abdullah used to perform four rak‘ahs. It was said to him: You objected to Hazrat Usman, and you yourself perform four rak‘ahs? Hazrat Abdullah replied: Disagreement (opposition) is the cause of evil.
