Al-Farafisa b. 'Umair al-Hanafi said that he learned Sura Yusuf (Al-Qur’an; 12) simply from the recitation of it by ‘Uthman b. ‘Affan in the morning prayer, owing to the great number of times he repeated it.
‘Amir b. Rabi'a said that they prayed the morning prayer behind ‘Umar b. al-Khattab and that he recited slowly in both rak'as Sura Yusuf and Sura al-Hajj (Al-Qur’an; 22). When someone remarked that he must have begun the prayer at break of day he replied that that was so.
Mu'adh b. ‘Abdallah. al-Juhani said that a man of Juhaina told him he had heard God’s Messenger reciting "When the earth is shaken”(Al-Qur’an; 99) in both rak'as of the morning prayer, but did not know whether he had forgotten, or whether he recited it on purpose.
