Abu Bakr al-Siddiq said, "Messenger of Allah, instruct me with words to say each morning and each evening."He said, "Say, 'O Allah, Originator of the heavens and the earth, Knower of the unseen and the seen, Lord of everything and its Sovereign, I bear witness that there is no god but You. I seek refuge in You from the evil of my own self, and from the evil of Satan and his incitement to associate partners with You.'"He said, "Say it when you rise in the morning, when you enter the evening, and when you lie down to sleep."
حدثنا مسدد حدثنا هشيم عن يعلى بن عطاء عن عمرو بن عاصم
أن أبا بكر الصديق رضي الله عنه قال يا رسول الله مرني بكلمات أقولهن إذا أصبحت وإذا أمسيت قال قل اللهم فاطر السموات والأرض عالم الغيب والشهادة رب كل شيء ومليكه أشهد أن لا إله إلا أنت أعوذ بك من شر نفسي وشر الشيطان وشركه قال قلها إذا أصبحت وإذا أمسيت وإذا أخذت مضجعك
[Sahih]. Tirmidhi narrated it in the Book of Supplications, Chapter "O Allah, Knower of the unseen and the seen, Originator of the heavens and the earth" (no. 3392), from the hadith of Yaala bin Ata through this chain, and he said, "Hasan sahih." Ibn Hibban also graded it sahih (no. 2349), as did Hakim (12/513), and Dhahabi agreed with him.
