Amr bin Dinar عمرو بن دينار الأثرم الجمحي · The Book of the Times (of Prayer)

"The Messenger of Allah (ﷺ) delayed A;-'Atamah one night, and 'Umar, may Allah be pleased with him, called out to him: 'The women and children have gone to sleep.' The Messenger of Allah (ﷺ) came out and said: 'No one is waiting for it except you.' At that time no prayer was offered except in Al-Madinah. Then he said: 'Pray it between the time when the twilight disappears and when one-third of the night has passed.'"

"If the Messenger of Allah (ﷺ) wanted to travel quickly, he would delay Zuhr until the time of 'Asr and combine them, and he would delay Maghrib until he combined it with 'Isha' when the twilight had disappeared."

"I never saw the Messenger of Allah (ﷺ) combine any two prayers except in Al-Muzdalifah, and on that day he prayed Subh before its time."
