Jami` at-Tirmidhi Book 48, Hadith 161
“I heard Abu Wa’il say: ‘`Abdullah bin Mas`ud said’ and I said to him: ‘Did you hear it from `Abdullah?’ He said: ‘Yes.’ And he narrated it in Marfu` form that he said: ‘There is none with more Ghirah than Allah, and due to this He prohibited the lewd sins, that which is apparent of them and that which is hidden. And there is none to whom praise is more beloved than Allah, and due to this, He praised Himself.’”
“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).’”
“O Messenger of Allah, teach me a supplication that I may supplicate with in my Salat.” He (ﷺ) said: “Say: ‘O Allah, I have wronged myself much, and none forgives sins except You. So forgive me with forgiveness from You, and have mercy upon me, indeed, You are the Forgiving, the Merciful (Allāhumma innī ẓalamtu nafsī ẓulman kathīran wa lā yaghfirudh-dhunūba illā anta faghfirlī maghfiratan min `indika warḥamnī innaka antal-Ghafūrur-Raḥīm).’”
