Yahya related to me from Malik from Hisham ibn Urwa from his father that the Messenger of Allah (ﷺ) prayed four raka prayers with only two rakas when at Mina, and that Abu Bakr prayed them at Mina with only two rakas, and that Umar ibn al-Khattab prayed them at Mina with only two rakas, and that Uthman prayed them at Mina with only two rakas for half of his khalifate, and then later completed them.
