Uthman bin Affan, may Allah be pleased with him, led us in four rakahs at Mina. When this was mentioned to Abdullah bin Masud, may Allah be pleased with him, he said, "To Allah we belong and to Him we return," then said, "I prayed with the Messenger of Allah ﷺ at Mina two rakahs, and I prayed with Abu Bakr al-Siddiq at Mina two rakahs, and I prayed with Umar bin Khattab, may Allah be pleased with him, at Mina two rakahs. How I wish that my share of these four rakahs were two accepted rakahs."
صلى بنا عثمان بن عفان ضي الله عنه بمنى أربع ركعات، فقيل ذلك لعبد الله بن مسعودضي الله عنه، فاسترجع ثم قال: صليت مع رسول ﷺ بمنى ركعتين، وصليت مع أبي بكر الصديق بمنى ركعتين، وصليت مع عمر بن الخطاب ضي الله عنه بمنى ركعتين فليت حظي من أربع ركعات ركعتان متقبلتان.
Bukhari narrated it in "Shortening the Prayer" (1084), and Muslim in "Prayer of Travelers" (695), both from Qutayba bin Saeed, who said, Abdul-Wahid narrated to us, from Amash, who said, Ibrahim narrated to us, who said, I heard Abdul-Rahman bin Yazid, and he mentioned it.Abu Dawud narrated it (1960) through the route of Abu Muawiya, from Amash, with an addition, "Then the roads split you apart, and I would have loved to have two accepted rak'ahs out of four." Amash said, Muawiya bin Qurra narrated to me, from his teachers, that Abdullah prayed four rak'ahs. He said, So he was asked, "You criticized Uthman, then you prayed four?" He said, "Disagreement is evil."In this narration, the teachers of Muawiya bin Qurra are unknown, but since some of them support one another, as it is said, this strengthens the report.Bayhaqi (3/144) said that it has also been narrated with a connected chain, and he brought it out through the route of Yunus bin Abu Ishaq, from Abu Ishaq, from Abdul-Rahman bin Yazid, who said, We were with Abdullah bin Masud at Jam. When he entered the masjid at Mina, he said, "How much has the commander of the believers prayed?" They said, "Four." So he prayed four. He said, So we said, "Did you not tell us that the Prophet ﷺ prayed two rak'ahs, and Abu Bakr prayed two rak'ahs?" He said, "Yes, and I am telling you that right now, but Uthman is an imam, so I will not oppose him, for disagreement is evil."In this chain is Abu Ishaq, who is Subayi, and he had mixed narrations in his later life and practiced tadlis. However, it has been narrated through other chains by Abu Yaala, Abu Awana, Bazzar, Tabarani in "Al-Awsat", and others, which mutually strengthen one another, so this addition is established through the sum of these routes.
