It was narrated that Uqbah bin Amr said:
I followed the Messenger of Allah (ﷺ) when he was riding, and I placed my hand on his foot and said : O Messenger of Allah, teach me Surah Hud and Surah Yusuf. He said: 'You will never recite anything greater before Allah than: Say: I seek refuge with (Allah), the Lord of the daybreak. And Say: I seek refuge with (Allah) the Lord of mankind.'
