(a) It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that Abdullah bin Mas'ud used to lead us in the morning prayer when the dawn broke, and lead the Maghrib prayer when the sun set, and then he would say: This is our prayer as it used to be with the Messenger of Allah (peace and blessings be upon him).
(b) It is narrated from al-Furafisah bin Umayr: I memorised Surah Yusuf from hearing the recitation of Sayyiduna Uthman (may Allah be pleased with him), because he used to recite it very often in the morning prayer.
