سنن النسائي

It was narrated that Abu Hurairah said: "The Messenger of Allah (ﷺ) said: This is 'Jibril, peace be upon you, he came to teach you your religion. He prayed Subh when the dawn appeared, and he prayed Zuhr when the sun had (passed its zenith), and he prayed 'Asr when he saw that the shadow of a thing was equal to its height, then he prayed Maghrib when the sub had set and it is permissible for the fasting person to eat. Then he prayed 'Isha' when the twilight had disappeared. Then he came to him the following day and prayed Subh when it had got a little lighter, then he prayed Zuhr when the shadow of a thing was equal to its height, then he prayed 'Asr when the shadow of a thing was equal to twice its height, then he prayed Maghrib at the same time as before, then he prayed 'Isha' when a short period of the night had passed. Then he said: 'The prayer is between the times when you prayed yesterday and the times when you prayed today.'"
