AbuBakr as-Siddiq said: Messenger of Allah! command me something to say in the morning and in the evening. He said: Say "O Allah, Creator of the heavens and the earth, Who knowest the unseen and the seen, Lord and Possessor of everything. I testify that there is no god 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 said: Say this in the morning.  

أَنَّ أَبَا بَكْرٍ الصِّدِّيقَ ؓ قَالَ يَا رَسُولَ اللَّهِ مُرْنِي بِكَلِمَاتٍ أَقُولُهُنَّ إِذَا أَصْبَحْتُ وَإِذَا أَمْسَيْتُ قَالَ قُلِ اللَّهُمَّ فَاطِرَ السَّمَوَاتِ وَالأَرْضِ عَالِمَ الْغَيْبِ وَالشَّهَادَةِ رَبَّ كُلِّ شَىْءٍ وَمَلِيكَهُ أَشْهَدُ أَنْ لاَ إِلَهَ إِلاَّ أَنْتَ أَعُوذُ بِكَ مِنْ شَرِّ نَفْسِي وَشَرِّ الشَّيْطَانِ وَشِرْكِهِ قَالَ قُلْهَا إِذَا أَصْبَحْتَ وَإِذَا أَمْسَيْتَ وَإِذَا أَخَذْتَ مَضْجَعَكَ  

“Abu Bakr said: ‘O Messenger of Allah, command me with something that I may say when I reach morning and evening.’ He said: ‘Say: “O Allah Knower of the Unseen and the Seen, Originator of the heavens and the earth, Lord of everything and its Possessor, I bear witness that there is none worthy of worship except You, I seek refuge from You from the evil of my soul and from the evil of Shaitan and his Shirk (Allāhumma ʿālimal-ghaibi wash-shahādati fāṭiras-samāwāti wal-arḍ, rabba kulli shai’in wa malīkahu, ash-hadu an lā ilāha illā anta, aʿūdhu bika min sharri nafsī wa min sharrish-shaiṭāni washirkihi).’” He said: ‘Say it when you reach morning, and evening, and when you go to bed.’”  

أَبُو بَكْرٍ يَا رَسُولَ اللَّهِ مُرْنِي بِشَيْءٍ أَقُولُهُ إِذَا أَصْبَحْتُ وَإِذَا أَمْسَيْتُ قَالَ قُلِ اللَّهُمَّ عَالِمَ الْغَيْبِ وَالشَّهَادَةِ فَاطِرَ السَّمَوَاتِ وَالأَرْضِ رَبَّ كُلِّ شَيْءٍ وَمَلِيكَهُ أَشْهَدُ أَنْ لاَ إِلَهَ إِلاَّ أَنْتَ أَعُوذُ بِكَ مِنْ شَرِّ نَفْسِي وَمِنْ شَرِّ الشَّيْطَانِ وَشِرْكِهِ قَالَ قُلْهُ إِذَا أَصْبَحْتَ وَإِذَا أَمْسَيْتَ وَإِذَا أَخَذْتَ مَضْجَعَكَ  

“I came to ʿAbdullah bin ʿAmr 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, ʿālimal-ghaibi wash-shahādati, lā ilāha illā anta, rabba kulli shai’in wa malīkahu, aʿūdhu bika min sharri nafsī wa min sharrish-shaiṭāni wa sharakihi, wa an aqtarifa ʿalā nafsī sū’an, aw ajurrahu ilā muslim).’”  

سَمِعْتَ مِنْ رَسُولِ اللَّهِ ﷺ فَأَلْقَى إِلَىَّ صَحِيفَةً فَقَالَ هَذَا مَا كَتَبَ لِي رَسُولُ اللَّهِ ﷺ قَالَ فَنَظَرْتُ فِيهَا فَإِذَا فِيهَا إِنَّ أَبَا بَكْرٍ الصِّدِّيقَ ؓ قَالَ يَا رَسُولَ اللَّهِ عَلِّمْنِي مَا أَقُولُ إِذَا أَصْبَحْتُ وَإِذَا أَمْسَيْتُ فَقَالَ يَا أَبَا بَكْرٍ قُلِ اللَّهُمَّ فَاطِرَ السَّمَوَاتِ وَالأَرْضِ عَالِمَ الْغَيْبِ وَالشَّهَادَةِ لاَ إِلَهَ إِلاَّ أَنْتَ رَبَّ كُلِّ شَيْءٍ وَمَلِيكَهُ أَعُوذُ بِكَ مِنْ شَرِّ نَفْسِي وَمِنْ شَرِّ الشَّيْطَانِ وَشَرَكِهِ وَأَنْ أَقْتَرِفَ عَلَى نَفْسِي سُوءًا أَوْ أَجُرَّهُ إِلَى مُسْلِمٍ قَالَ هَذَا حَدِيثٌ حَسَنٌ غَرِيبٌ مِنْ هَذَا الْوَجْهِ
