English Translation
And through their chain of narration from Malik, from Hisham ibn Urwah, from his father, that he heard Abdullah ibn Amir say: We prayed the morning prayer behind Umar ibn al-Khattab (may Allah be pleased with him), and he recited Surah Yusuf and Surah al-Hajj in a slow recitation. Hisham said: I said, "By Allah, then he must have been standing since the break of dawn." He said: "Indeed."
