Ibn Shihab narrates: Once, Umar bin Abdul Aziz was sitting on the pulpit (i.e., delivering a sermon) and he delayed the Asr prayer a little. So Urwah bin Zubair spoke up: Jibreel (peace be upon him) informed the Prophet (peace be upon him) about the timings of the prayer. Umar bin Abdul Aziz said to him: "Try to understand what you are saying." So Urwah said: I heard Bashir bin Abu Mas'ud narrate this, he says: I heard Sayyiduna Abu Mas'ud Ansari (may Allah be pleased with him) narrate this, he said: I heard the Prophet (peace be upon him) say: "Once Jibreel (peace be upon him) descended and informed me about the timings of the prayer. I prayed with him, then I prayed the next prayer with him, then I prayed the next prayer with him. He counted the five prayers on his fingers." (Sayyiduna Abu Mas'ud Ansari [may Allah be pleased with him] narrates:) I remember about the Prophet (peace be upon him) that he would perform the Zuhr prayer when the sun had declined, but when the heat was intense, he would delay this prayer. I saw him perform the Asr prayer when the sun was high and bright, there was no yellowness in it yet (i.e., the sunlight had not faded), and a person could reach Dhul-Hulaifah before sunset after performing the prayer. The Prophet (peace be upon him) would perform the Maghrib prayer when the sun had set. He (peace be upon him) would perform the Isha prayer when the horizon had become dark, and sometimes he (peace be upon him) would delay it so that people could gather. (The narrator says: In one narration, these words are present:) Sometimes the Prophet (peace be upon him) would perform the Fajr prayer in darkness and sometimes in brightness, but then after that, he (peace be upon him) started performing it only in darkness, and this remained his practice until his passing. He never performed this prayer in brightness again.
