‘Abdallah b. ‘Amr reported Allah's Messenger ﷺ as saying, “Knowledge has three categories

He told how Abu Bakr said he had asked Allah's Messenger ﷺ to command him something to say in the morning and the evening, and he had told him to say, “O Allah, 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 Allah but Thee; I seek refuge in Thee from the evil within myself, from the evil of the devil and his [incitement to] attributing partners [to Allah].”* 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 Allah), or as sharah (snare). The former is preferred. Cf. Mirqat, ili, 99. Tirmidhi, Abu Dawud and Darimi transmitted it.

Aban b. ‘Uthman said he heard his father quoting Allah's Messenger ﷺ as saying that if anyone says three times every morning and evening, “In the name of Allah, 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 Allah 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.”

‘Abdallah [i.e. ‘Abdallah b. Mas’ud.] said that the Prophet (ﷺ) used to say in the evening, “We have come to the evening, and in the evening the dominion belongs to Allah; Praise be to Allah; there is no Allah but Allah alone who has no partner; to Him belongs the dominion, to Him praise is due, and He is omnipotent. My Lord, I ask Thee for the good of what this night contains and the good of what comes after it; I seek refuge in Thee from the evil of what this night contains and the evil of what comes after it; my Lord, I seek refuge in Thee from indolence and from the evil of old age, or infidelity."* A version has, "From the evil of old age and pride. My Lord, I seek refuge in Thee from a punishment in hell and a punishment in the grave." In the morning he said that also

One of the Prophet's daughters said that he used to teach her, telling her to say in the morning, "Glory be to Allah, and I begin with praise of Him; there is no power but in Allah; what Allah wills comes to pass, and what He does not will does not come to pass; I know that Allah is omnipotent and that Allah 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. Abu Dawud transmitted it.

Ibn ‘Abbas reported Allah's Messenger ﷺ as saying that if anyone repeats in the morning, "So Glory be to Allah in the evening and in the morning; to Him is the praise in the heavens and the earth; and in the late evening and at noon .. . thus shall you be brought forth," [Qur'an, xxx, 17-19.] he will get that day what he has missed; and if anyone repeats these words in the evening he will get that night what he has missed. Abu Dawud transmitted it.

Abu ‘Ayyash reported Allah's Messenger ﷺ as saying that if anyone says in the morning, “There is no Allah but Allah alone who has no partner; to Him belongs the dominion, to Him praise is due, and He is omnipotent,” he will have a reward equivalent to that for setting free a slave from among the descendants of Ishmael, will have ten good deeds recorded for him, will have ten evil deeds deducted from him, will be advanced ten degrees, and will be guarded from the devil till the evening. If he says them in the evening he will have a similar recompense till the morning. Hammad b. Salama said that a man saw Allah's Messenger ﷺ in a dream and said, “ Messenger of Allah , Abu ‘Ayyash is relating such and such on your authority,” to which he received the reply, “Abu ‘Ayyash has spoken the truth.” Abu Dawud and Ibn Majah transmitted it.

Al-Harith b. Muslim at-Tamimi quoted his father as saying that Allah's Messenger ﷺ told him secretly to say seven times when he had finished the sunset prayer, before speaking to anyone, “O Allah, protect me from hell”; for if he said that and died that night, exemption from it would be recorded for him. He also told him to say that when he had prayed the morning prayer, for if he died that day, exemption from it would be recorded for him. Abu Dawud transmitted it.

Ibn ‘Umar said that Allah's Messenger ﷺ never failed to use these words evening and morning, “O Allah, I ask Thee for security in this world and the next; O Allah, I ask Thee for forgiveness and security in my religion and my worldly affairs, in my family and my property; O Allah, conceal my faults [cf. Mirqat, iii, 103.] and keep me safe from the things which I fear; O Allah, guard me in front of me and behind me, on my right hand and on my left, and from above me; and I seek refuge in Thy greatness from receiving unexpected harm from below me.” Waki‘ said he meant being swallowed up by the earth. Abu Dawud transmitted it.

Anas reported Allah's Messenger ﷺ as saying that if anyone says in the morning, “O Allah, in the morning we call Thee, the bearers of Thy Throne, Thy angels and all Thy creatures to witness that Thou art Allah than whom alone there is no god, being without a partner, and that Muhammad is Thy servant and messenger,” Allah will forgive him any sins he commits that day; and if he says it in the evening, Allah will forgive him any sins he commits that night. Tirmidhi and Abu Dawud transmitted it, Tirmidhi saying this is a gharib tradition.

Thauban reported Allah's Messenger ﷺ as saying that if any Muslim says three times evening and morning, "I am pleased with Allah as Lord, with Islam as religion, and with Muhammad as Prophet," Allah will certainly please him on the day of resurrection. Ahmad and Tirmidhi transmitted it.
