Mishkat al-Masabih 8 The Excellent Qualities of the Qur’an كتاب فضائل القرآن 54

وَعَنْ عُقْبَةَ بْنِ عَامِرٍ قَالَ: قُلْتُ يَا رَسُولَ اللَّهِ أَقْرَأُ سُورَةَ (هُودٍ) أَوْ سُورَةَ (يُوسُفَ) ؟ قَالَ: ” لَنْ تَقْرَأَ شَيْئًا أَبْلَغَ عِنْدَ اللَّهِ مِنْ (قُلْ أَعُوذُ بِرَبِّ الْفَلَقِ) رَوَاهُ أَحْمد وَالنَّسَائِيّ والدارمي

‘Uqba b. ‘Āmir said that when he asked God’s messenger whether he should recite sūra Hūd (Qur’ān, 11) or sūra Yūsuf (Qur’ān, 12), he told him he could recite nothing more effective with God than “Say, I seek refuge in the Lord of the dawn.” Ahmad, Nasā’i and Dārimī transmitted it.
