It is narrated from Hazrat Uqbah bin Aamir (may Allah be pleased with him) that once I was walking ahead of the Prophet’s (peace and blessings be upon him) mount on a path, when suddenly the Prophet (peace and blessings be upon him) said to me, "O Uqbah! Why don’t you ride?" But I thought of the greatness of the Prophet (peace and blessings be upon him), that how could I ride on his mount. After a little while, the Prophet (peace and blessings be upon him) again said, "O Uqbah! Why don’t you ride?" This time I feared that perhaps this might be considered disobedience, so when the Prophet (peace and blessings be upon him) dismounted, I mounted, and after going a short distance, I dismounted. The Prophet (peace and blessings be upon him) mounted again and said, "O Uqbah! Shall I not teach you two surahs which are better than all the surahs that people recite?" I said, "Why not, O Messenger of Allah! (peace and blessings be upon him)" So the Prophet (peace and blessings be upon him) taught me Surah Al-Falaq and Surah An-Naas. Then the prayer was established, the Prophet (peace and blessings be upon him) went forward and recited these two surahs in the prayer. Then, passing by me, he said, "O Uqbah! What do you understand? Recite these two surahs when you go to sleep and when you wake up."
