Ibrahim al-Nakha'i إبراهيم النخعي · The Book of the Times (of Prayer)

"The Prophet (ﷺ) prayed Zuhr when the length of (a person's shadow) was between three and five feet in summer, and between five and seven feet in winter."

"The Messenger of Allah (ﷺ) got distracted and did not pray the two Rak'ahs before 'Asr so he prayed them after 'Asr."
