And from him, from Ya‘qub ibn Yazid, from Al-Hasan ibn Ali al-Washsha’, from Ahmad ibn ‘Umar, from Abu al-Hasan عليه السلام, who said: I asked him about the time of Dhuhr and ‘Asr. He said: “The time of Dhuhr is from when the sun declines (from the meridian) until the shadow reaches the length of one forearm, and the time of ‘Asr is from one and a half forearms to two forearms.”
