(3) باب فِي وَقْتِ صَلاَةِ النَّبِيِّ صلى الله عليه وسلم وَكَيْفَ كَانَ يُصَلِّيهَا
Muhammad b. 'Amr b. al-Hasan reported:
We asked Jabir about the time of the prayer of the Messenger of Allah (ﷺ). He said: He used to offer the Zuhr prayer in the midday heat, the 'Asr prayer when the sun was bright, the Maghrib prayer when the sun had completely set, the Isha prayer early when many people were present, but late if there were few, and the Fajr prayer in the darkness (of the dawn).
