Explanation
This invocation is among the remembrances prescribed for morning and evening. It was taught by the Prophet ﷺ to Abū Bakr al-Ṣiddīq (may Allah be pleased with him) when he said, “Teach me something to say.” The Prophet ﷺ then instructed him with a dhikr and supplication to recite each time he enters the morning and each time he enters the evening. He ﷺ said:

“Say: ‘O Allah, Originator of the heavens and the earth, Knower of the unseen and the seen, Lord of everything and its Sovereign…’ ”

“Say: O Allah, Originator of the heavens and the earth”—that is, “O Allah, O Originator of the heavens and the earth.” Originating them means that He created them without any previous model; rather, He fashioned them and brought them out of non-existence with no precedent whatsoever.

“Knower of the unseen and the seen” means that He knows what is hidden from creation and what they witness, for Allah knows the present, the future, and the past.

“Lord of everything and its Sovereign” means “O Lord of everything and its Sovereign.” Allah is the Lord of all things and He is the Sovereign of all things. The difference in this ḥadīth between rabb (Lord) and mālik (Sovereign/Owner) is that rabb is the one who brings things into existence, their Creator, whereas mālik is the one who disposes of them as He wills.

“I bear witness that there is no deity but You”—I acknowledge with my tongue and my heart that none is truly worthy of worship except You; whatever is worshiped besides Allah is false. No one has any right to worship except Allah alone.

“I seek refuge in You from the evil of my own self,” for the soul harbors evils, as the Most High said: “I do not absolve my own self; surely the soul is prone to evil, unless my Lord shows mercy” (Q 12:53). If Allah does not shield you from the evils of your own self, it will harm you and command you
