Narrated ‘Abdallah said that the Prophet used to say in the evening, “We have come to the evening, and in the evening the dominion belongs to God; praise be to God; there is no god but God alone who has no partner; to Him belongs the dominion, to Him praise is due, and He is omnipotent. My Lord, I ask Thee :
"We have come to the morning, and in the morning the dominion belongs to God..."
*The transmitter was not sure which word was used.
Abu Dawud and Tirmidhi transmitted it. Tirmidhi did not mention "from the evil of infidelity" in his version.
Aban b. ‘Uthman said he heard his father quoting God’s messenger as saying that if anyone says three times every morning and evening, “In the name of God, when whose name is mentioned nothing in earth or heaven can cause harm, and He is the Hearer, the Knower,” he will not be harmed by anything. Aban was afflicted by some paralysis, and when a man began to look at him Aban would say, “Why are you looking at me? The tradition is as I told it to you, but I did not say the words that day in order that God might carry out what He had decreed for me.”
Tirmidhi, Ibn Majah and Abu Dawud transmitted it. Abu Dawud’s version has, “He will not suffer sudden affliction till the morning, and if anyone says it in the morning he will not suffer sudden affliction till the evening.”
One of the Prophet's daughters said that he used to teach her, telling her to say in the morning, "Glory be to God, and I begin with praise of Him; there is no power but in God; what God wills comes to pass, and what He does not will does not come to pass; I know that God is omnipotent and that God has comprehended everything in knowledge;" for whoever says it in the morning will be guarded till the evening, and whoever says it in the evening will be guarded till the morning.
He told how Abu Bakr said he had asked God’s messenger to command him something to say in the morning and the evening, and he had told him to say, “O God, who knowest the unseen and the seen, Creator of the heavens and the earth, Lord and Possessor of everything, I testify that there is no god but Thee; I seek refuge in Thee from the evil within myself, from the evil of the devil and his .”* He instructed him to say it morning and evening, and when he went to bed.
*The Arabic word may be read either as shirk (attributing a partner to God), or as sharah
(snare). The former is preferred. Cf. Mirqat, ili, 99.
