Bismillāhi ‘l-ladhī lā yaḍurru ma`a-smihi shay'un fil-'arḍi wa lā fis-samā' wa huwas-Samī `ul-`Alīm. In the Name of Allah, Who with His Name nothing can cause harm in the earth nor in the heavens, and He is the All-Hearing, the All-Knowing. (Recite three times in Arabic). Reference: "Whoever recites it three times in the morning will not be afflicted by any calamity before evening, and whoever recites it three times in the evening will not be overtaken by any calamity before morning." Abu Dawud 4/323, At-Tirmidhi 5/465, Ibn Majah 2/332, Ahmad. Ibn Majah's chain of transmission is good (Hasan), Ibn Baz, p. 39.

'Uthman said that he heard the Prophet, may Allah bless him and grant him peace, say, "A person will not be harmed by anything if he says every morning and evening 33 times, 'In the Name of Allah by whose Name nothing in the earth or the heaven is harmed. He is the All-Hearing, the All-Knowing.'"

The Messenger of Allah (ﷺ) said: `Whoever says in the Name of Allah, with whose name nothing on earth or in heaven can cause harm, and He is the All-Hearing, All-Knowing, nothing will harm him.`

I heard `Uthman bin `Affan (رضي الله عنه) say: The Messenger of Allah (ﷺ) said: `Whoever says at the beginning of the day or the beginning of the night, ‘In the Name of Allah with Whose name nothing on earth or in heaven can cause harm, and he is the All-Hearing. All-Knowing.` three times, nothing will harm him during that day or that night.”

`Whoever says, `In the Name of Allah with Whose name nothing on earth or in heaven can cause harm, and he is the All-Hearing, All-Knowing.` three times, will not be struck unawares by calamity until night comes, and whoever says it in the evening will not be struck unawares by calamity until morning comes, in sha` Allah.”

“I heard `Uthman bin `Affan (ra) saying: ‘The Messenger of Allah (saws) said: “There is no worshiper who says, in the morning of every day, and the evening of every night: ‘In the Name of Allah, who with His Name, nothing in the earth or the heavens can cause harm, and He is the Hearing, the Knowing (Bismillāh, alladhi lā yaḍurru ma`a ismihi shai'un fil-arḍi wa lā fis-samā', wa huwas-Samī`ul `Alīm)’ – three times, (except that) nothing shall harm him.” And Aban had been stricken with a type of semi-paralysis, so a man began to look at him, so Aban said to him, “What are you looking at? Indeed the Hadith is as I reported it to you, but I did not say it one day, so Allah brought about His decree upon me.”

Aban ibn Uthman said: I heard Uthman ibn Affan (his father) say: I heard the Messenger of Allah (saws) say: If anyone says three times: "In the name of Allah, when Whose name is mentioned nothing on Earth or in Heaven can cause harm, and He is the Hearer, the Knower" he will not suffer sudden affliction till the morning, and if anyone says this in the morning, he will not suffer sudden affliction till the evening.

Aban was afflicted by some paralysis and when a man who heard the tradition began to look at him, he said to him: Why are you looking at me? I swear by Allah, I did not tell a lie about Uthman, nor did Uthman tell a lie about the Prophet (saws), but that day when I was afflicted by it, I became angry and forgot to say them.

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.”

"I heard the Messenger of Allah (saas) say: "There is no person who says, in the morning and evening of every day: Bismillahil-ladhi la yadurru ma'a ismihi shay'un fil-ardi wa la fis-sama'i wa Huwas-Sami'ul-'Alim (In the name of Allah with Whose Name nothing on earth or in heaven harms, and He is the All-Seeing, All-Knowing), three times, and is then harmed by anything.'" (Hasan)He (one of the narrators) said: "Aban had been stricken with paralysis on one side of his body, and a man started looking at him. Aban said: 'Why are you looking at me? The Hadith is as I have narrated it to you, but I did not say it that day, so that the decree of Allah might be implemented.'"
