Bayhaqi 1710 — The end of the time of Zuhr and the start of the time

(a) It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Jibril (peace be upon him) led me in prayer twice near the House (of Allah). He led me in Zuhr when the sun had declined and (the shadow) was the size of a sandal strap; then he led me in Asr when the shadow of everything had become equal to it."
(b) He narrated the hadith, and in it he said: "Then the next day he led me in Zuhr when the shadow of everything had become equal to it; then he led me in Asr when the shadow of everything had become twice its length."
(c) He then narrated the hadith, and at its end it says: Then he turned to me and said: "O Muhammad! This is the time of the prophets before you, and the time is between these two times."
(d) The position of Imam al-Shafi'i (may Allah have mercy on him) is that the beginning of the time of Asr is separate from the end of the time of Zuhr, and that the statement of Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) said: "He led me in Asr when the shadow of everything was equal to it," means: when the shadow of everything had fully become equal to it and had exceeded that by the smallest amount. And it reached me from some of the students of Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that there is a narration with the meaning of what I have described, and I think he reported it from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both).
