Abu Razin said: Nafi' bin al-Azraq argued with Sayyiduna Ibn Abbas (may Allah be pleased with them both) and asked: Do you find the five prayers in the Book of Allah? He said: Yes. Then he recited: "So glorify Allah when you reach the evening" [Surah al-Rum: 17], this is Maghrib; "and when you reach the morning" [Surah al-Rum: 17], this is Fajr; "and in the late afternoon" [Surah Maryam: 11], this is Asr; "and when you are at noon" [Surah al-Rum: 18], he said: this is Zuhr; "and after the Isha prayer" [Surah al-Nur: 58], he said: this is the Isha prayer.
