Jami` at-Tirmidhi Book 48, Hadith 159
“When one of you becomes frightened during sleep, then let him say: ‘I seek refuge in Allah’s Perfect Words from His anger, His punishment, and the evil of His creatures, from the whisperings of the Shayatin, and that they should come (A`ūdhu bikalimātillāhit-tāmmati min ghaḍabihī wa `iqābihī wa sharri `ibādih, wa min hamazātish-shayāṭīni wa an yaḥḍurūn).’ For verily, they shall not harm him.” He said: “So `Abdullah bin `Amr used to teach it to those of his children who attained maturity, and those of them who did not, he would write it on a sheet and then hang it around his neck.”
"O Allah! Verily, I ask You for the bounty's completion (Allāhumma, innī as'aluka tamāman-ni`mah)." So he (ﷺ) said: "What thing is the bounty's completion?" He said: "A supplication that I made, that I hope for good by it." He (ﷺ) said: "Indeed, part of the bounty's completion is the entrance into Paradise, and salvation from the Fire." And he (ﷺ) heard a man while he was saying: "O Possessor of Majesty and Honor (Yā Dhal-Jalāli wal-Ikrām)" So he (ﷺ) said: "You have been responded to, so ask." And the Prophet (ﷺ) heard a man while he was saying: "O Allah, indeed, I ask You for patience (Allāhumma, innī as'alukaṣ-ṣabr)" He (ﷺ) said: "You have asked Allah for trial, so ask him for Al-`Āfiyah."
“I came to `Abdullah bin `Amr and said to him: ‘Report something to me that you heard from the Messenger of Allah (ﷺ).’ So he set forth before me a scroll and said: ‘This is what the Messenger of Allah (ﷺ) wrote for me.’” He said: “So I looked in it and found in it: ‘Indeed, Abu Bakr As-Siddiq, may Allah be pleased with him, said: “O Messenger of Allah, teach me what to say at morning and afternoon.” He said: “O Abu Bakr, say: ‘O Allah, Creator of the heavens and the earth, Knower of the unseen and the seen, there is none worthy of worship except You, Lord of everything and its Owner, I seek refuge in You from the evil of my soul and from the evil of Shaitan and his Shirk, or that I should do some evil to myself or bring it upon a Muslim (Allāhumma fāṭiras-samāwāti wal-arḍi, `ālimal-ghaibi wash-shahādati, lā ilāha illā anta, rabba kulli shai’in wa malīkahu, a`ūdhu bika min sharri nafsī wa min sharrish-shaiṭāni wa sharakihi, wa an aqtarifa `alā nafsī sū’an, aw ajurrahu ilā muslim).’”
