Hazrat Urwah bin Zubair heard from Sayyiduna Abdullah bin Amir bin Rabi’ah (may Allah be pleased with him), who said: We prayed behind Sayyiduna Umar bin Khattab (may Allah be pleased with him) the morning prayer, and he recited Surah Yusuf and Surah Hajj slowly and distinctly. Hazrat Urwah said: By Allah! At that time, they must have been standing for prayer when true dawn appeared. Sayyiduna Abdullah (may Allah be pleased with him) said: Yes.
