'Uthman prayed four rak'ahs at Mina. 'Abd Allah (b. Mas'ud) said: I prayed two rak'ahs along with the Prophet ﷺ and two rak'ahs along with 'Umar. The version of Hafs added: And along with 'Uthman during the early period of his caliphate. He ('Uthman) began to offer complete prayer (i.e. four rak'ahs) later on. The version of Abu Mu'awiyah added: Then your modes of action varied. I would like to pray two rak'ahs acceptable to Allah instead of four rak'ahs. Al-A'mash said: Mu'awiyah b. Qurrah reported to me from his teachers: 'Abd Allah (b. Mas'ud) once prayed four rak'ahs. He was told: You criticized 'Uthman but you yourself prayed four ? He replied: Dissension is evil.
