bayhaqi:1684Abū ʿAbdullāh al-Ḥāfiẓ And ʾAbū Saʿīd b. Abū ʿAmr > Abū al-ʿAbbās Muḥammad b. Yaʿqūb > Yaḥyá b. Abū Ṭālib > ʿAbd al-Wahhāb b. ʿAṭāʾ > ʿAmr b. ʿUbayd

[Machine] About Al-Hasan's saying, "Glorified be Allah when you sleep" [Surah Ar-Rum 17], he said that the prayer for Maghrib and Isha is "when you become evening" [Surah Ar-Rum 17]. The prayer for Fajr is "and for Him is praise in the heavens and the earth at nightfall" [Surah Ar-Rum 17]. Al-Asr is "when you appear" [Surah Ar-Rum 18]. Adh-Dhuhr is "and for Him is praise in the heavens and the earth at noon" 1685. He said that Abd Allah bin Wahb informed us about Sa'id, who narrated the same as him 1686. Abd Allah bin Wahb also informed us that Amru informed us about Al-Hasan's saying, "Establish prayer at the two ends of the day" [Surah Hud 114]. He said that the prayer for Fajr is one end, and the other end is Dhuhr and Asr. "And [offer] the portion of the night" [Surah Hud 114] refers to Maghrib and Isha.
