كتاب الاستعاذة
Read the English translation first, with the original Arabic directly underneath.
It was narrated that 'Uqbah bin 'Amir said:
"I came to the Messenger of Allah [ﷺ] while he was riding, and I put my hand on his foot and said: 'Teach me Surah Hud, teach me Surah Yusuf. He said: 'You will never recite anything more precious before Allah, the Mighty and Sublime, than: 'Say: I seek refuge with (Allah) the Lord of the daybreak.'"
لَنْ تَقْرَأَ شَيْئًا أَبْلَغَ عِنْدَ اللَّهِ عَزَّ وَجَلَّ مِنْ { قُلْ أَعُوذُ بِرَبِّ الْفَلَقِ }
