Sayyiduna Uqbah bin Amir (may Allah be pleased with him) says: I clung to the footsteps of the Messenger of Allah (peace and blessings be upon him) and said: O Messenger of Allah! Teach me Surah Hud and Surah Yusuf. The Prophet (peace and blessings be upon him) said to me: O Uqbah bin Amir! No surah has been recited that is more beloved to Allah Almighty and more eloquent, except Surah al-Falaq. (After hearing this hadith) Abu Imran never left this surah and would always recite it in the Maghrib prayer.
