The Prophet ﷺ used to say whenever he left his house, "In the name of Allah, I place my trust in Allah. O Allah, we seek refuge in You from slipping or going astray, from wronging others or being wronged, and from acting ignorantly or having others act ignorantly toward us."
أن النبي ﷺ كان إذا خرج من بيته قال: بسم الله توكلت على الله، اللهم إنا نعوذ بك من أن نزل أو نضل أو نظلم او نظلم أو نجهل أو يجهل علينا.
Recorded by Abu Dawud (5094), Tirmidhi (3427), Nasai (5486), Ibn Majah (3884), Ahmad (26616, 26704), Ibn Sunni in Amal al-Yawm wal-Layla (177), and Hakim (1/519), all of them through various routes from Mansur, from Shaybi, from Umm Salama, as I have related it, with the wording being that of Tirmidhi. Tirmidhi said, "This is a hasan sahih hadith." Hakim said, "This is a sahih hadith meeting the criteria of the two Shaykhs, though they did not include it. Someone might mistakenly imagine that Shaybi did not hear from Umm Salama, but that is not so, for he visited both Ayesha and Umm Salama, and then narrated extensively from both of them." This is what he said.Ibn Hajar responded to this in Nataij Afkar (1/160-161), saying, "This is what he said! Yet he contradicted this in his own Ulum al-Hadith, where he stated that Shaybi did not hear from Ayesha. And Ali bin Madini said in his book Ilal, Shaybi did not hear from Umm Salama, which would make this hadith disconnected." Yet before that he had said, "This is a hasan hadith," and a disconnected hadith cannot be called hasan, for it falls among the categories of daif. We must therefore understand Ali bin Madini's statement as referring explicitly to the establishment of an actual meeting, according to his own standard and that of his student Bukhari regarding the requirement of meeting, whereas the majority, as is well known, are satisfied with mere contemporaneity, which is indeed established for Shaybi, since he was born around the year twenty and died after the year one hundred, while Umm Salama died in the year 62 AH, so he would have lived through about forty years of her life. Abu Dawud Sijistani explicitly stated that Shaybi heard from Umm Salama, and Tirmidhi, Hakim, Nawawi, and Ibn Hajar all agreed that this is a sahih or hasan hadith, and that is the correct view. And Allah grants success.Similar in meaning is what was narrated from Anas bin Malik, who said that the Messenger of Allah ﷺ said, "When a man leaves his house and says, 'In the name of Allah, I place my trust in Allah, there is no power and no strength except with Allah,' it is said at that moment, 'You have been guided, sufficed, and protected,' and the devils move away from him. Then another devil says, 'How can you approach a man who has been guided, sufficed, and protected?'"Recorded by Abu Dawud (5095), Tirmidhi (3426), Nasai in Amal al-Yawm wal-Layla (89), Ibn Sunni (179), and Ibn Hibban (822), all of them through various routes from Ibn Jurayj, who said, from Ishaq bin Abdullah bin Abu Talha, from Anas bin Malik, as I have related it, with the wording being that of Abu Dawud. Tirmidhi said, "This is a hasan gharib hadith, we know it only through this route." This is what he said!Yet he said in Ilal al-Kabir (2/911), "I asked Muhammad, meaning Bukhari, about this hadith, and he said, 'They narrated to me from Yahya bin Saeed, from Ibn Jurayj, this hadith, but I do not know of any narration from Ibn Jurayj from Ishaq bin Abdullah bin Abu Talha other than this one, nor do I know that he heard it directly from him.'" End of quote.Daraqutni said in Ilal (12/13), "The correct view is that Ibn Jurayj did not hear it directly from Ibn Ishaq." End of quote.Ibn Hajar said in Nataij Afkar (1/164), "Its narrators are the narrators of the sahih collections, and that is why Ibn Hibban graded it sahih, but this flaw was hidden from him." He then mentioned the statements of Bukhari and Daraqutni.It was also narrated from Abu Hurairah that when the Prophet ﷺ left his house, he would say, "In the name of Allah, there is no power and no strength except with Allah, reliance is placed upon Allah."Recorded by Ibn Majah (3885), Bukhari in Adab al-Mufrad (1197), Ibn Sunni in Amal al-Yawm wal-Layla (178), and Hakim (1/519), all of them through various routes from Hatim bin Ismail, from Abdullah bin Husayn bin Ata bin Yasar, from Suhayl bin Abu Salih, from his father, from Abu Hurairah, who said, as I have related it. Hakim said, "This is a sahih hadith meeting the criteria of Muslim." This is what he said! Yet in its chain is Abdullah bin Husayn bin Ata, from whom Muslim did not narrate, and he is daif. Abu Zura criticized this hadith on account of him. See the questions of Barzai to him (2/537-538).It was also narrated from him that the Prophet ﷺ said, "When a man leaves through the door of his house, or the door of his home, two angels assigned to him accompany him. When he says, 'In the name of Allah,' they say, 'You have been guided.' When he says, 'There is no power and no strength except with Allah,' they say, 'You have been protected.' When he says, 'I place my trust in Allah,' they say, 'You have been sufficed.'" He said, "Then his two companion devils meet him and say, 'What can you two want from a man who has been guided, sufficed, and protected?'"Recorded by Ibn Majah (3886), Tabarani in Dua (409), and Ibn Adi (7/2586), all of them through various routes from Ibn Abu Fudayk, who said, Harun bin Harun narrated to me, from Araj, from Abu Hurairah, who said, as I have related it. Harun bin Harun is Ibn Abdullah Taymi, daif by the agreement of the scholars. Ibn Hibban said, "He used to narrate fabricated material while attributing it to reliable narrators, so it is not permissible to rely on him as evidence."
