While I was leading the mount of the Messenger of Allah ﷺ through one of those mountain passes, he said, "Will you not ride, Uqba?"I felt it would be disrespectful to ride the mount of the Messenger of Allah ﷺ.Then he said again, "Will you not ride, Uqba?"I feared that refusing might be an act of disobedience, so he dismounted and I rode for a short while, then I dismounted and the Messenger of Allah ﷺ mounted again.Then he said, "Shall I teach you two surahs that are among the best surahs people recite?"He taught me "Say, I seek refuge in the Lord of the daybreak" [Falaq 113:1] and "Say, I seek refuge in the Lord of mankind" [Nas 114:1].Then the call to prayer was given, and he stepped forward and recited them in the prayer. Afterwards he passed by me and said, "What did you think, Uqba bin Amir? Recite them whenever you lie down and whenever you rise."
أخبرني محمود بن خالد قال حدثنا الوليد قال حدثني ابن جابر عن القاسم أبي عبد الرحمن
بينا أقود برسول الله ﷺ في نقب من تلك النقاب إذ قال ألا تركب يا عقبة فأجللت رسول الله ﷺ أن أركب مركب رسول الله ﷺ ثم قال ألا تركب يا عقبة فأشفقت أن يكون معصية فنزل وركبت هنيهة ونزلت وركب رسول الله ﷺ ثم قال ألا أعلمك سورتين من خير سورتين قرأ بهما الناس فأقرأني قل أعوذ برب الفلق و قل أعوذ برب الناس فأقيمت الصلاة فتقدم فقرأ بهما ثم مر بي فقال كيف رأيت يا عقبة بن عامر اقرأ بهما كلما نمت وقمت
