Say (O Muhammad): O mankind! Lo! I am the messenger of Allah to you all - (the messenger of) Him unto Whom belongeth the Sovereignty of the heavens and the earth. There is no Allah save Him. He quickeneth and He giveth death. So believe in Allah and His messenger, the Prophet who can neither read nor write, who believeth in Allah and in His Words, and follow him that haply ye may be led aright.

Times of the Prayers
Chapter: The time of the Asr prayer
Narrated Saiyar bin Salama:
I along with my father went to Abu- Barza Al-Aslami and my father asked him, "How Allah's Messenger (ﷺ) used to offer the five compulsory congregational prayers?" Abu- Barza said, "The Prophet (ﷺ) used to pray the Zuhr prayer which you (people) call the first one at midday when the sun had just declined The `Asr prayer at a time when after the prayer, a man could go to the house at the farthest place in Medina (and arrive) while the sun was still hot. (I forgot about the Maghrib prayer). The Prophet (ﷺ) Loved to delay the `Isha which you call Al- `Atama [??] and he disliked sleeping before it and speaking after it. After the Fajr prayer he used to leave when a man could recognize the one sitting beside him and he used to recite between 60 to 100 Ayat (in the Fajr prayer) .
