It is narrated from Sayyiduna Abu Bakr as-Siddiq (may Allah be pleased with him) that he said to the Messenger of Allah (peace and blessings of Allah be upon him): Teach me a supplication which I may recite in my prayer.

Sayyiduna Abdullah bin Amr bin al-As narrates that Abu Bakr Siddiq (may Allah be pleased with him) said to the Messenger of Allah (peace and blessings be upon him): "O Messenger of Allah (peace and blessings be upon him), teach me a supplication which I may recite in my prayer and in my home." The Prophet (peace and blessings be upon him) said: "Recite this supplication «‏‏‏‏اللّٰهُمَّ إِنِّي ظَلَمْتُ نَفْسِي ظُلْمًا كَبِيرًا وَلَا يَغْفِرُ الذُّنُوبَ إِلَّا أَنْتَ، فَاغْفِرْ لِي مَغْفِرَةً مِنْ عِنْدِكَ، وَارْحَمْنِي إِنَّكَ أَنْتَ الْغَفُورُ الرَّحِيمُ» ‏‏‏‏ 'O Allah, indeed I have wronged myself greatly, and there is none who forgives sins except You, so grant me forgiveness and mercy from Yourself, surely You are the Most Forgiving, Most Merciful.'"

Lady Aisha (may Allah be pleased with her) narrates that when Surah «‏‏‏‏إِذَا جَاءَ نَصْرُ اللَّهِ وَالْفَتْحُ» ‏‏‏‏, that is, Surah An-Nasr, was revealed in its entirety, I heard the Messenger of Allah (peace and blessings be upon him) reciting this tasbih in every prayer: «‏‏‏‏سُبْحَانَكَ اللّٰهُمَّ وَبِحَمْدِكَ اللّٰهُمَّ اغْفِرْلِي» ‏‏‏‏ "O Allah, You are Pure with Your praises, O Allah, forgive me."

Hazrat Abu Malik Ashja'i narrates from his esteemed father, who says that we used to present ourselves before the Messenger of Allah (peace be upon him) in the morning. Men and women would come and ask, "O Messenger of Allah, when I pray, how should I supplicate?" The Prophet (peace be upon him) said: "Supplicate in this way «‏‏‏‏اللّٰهُمَّ اغْفِرْلِي، وَارْحَمْنِي، وَاهْدِنِي، وَعَافِنِي، وَارْزُقْنِي» ‏‏‏‏ 'O Allah, forgive me, have mercy on me, guide me, grant me well-being, and provide for me.' Then all the good of your world and Hereafter will be gathered for you."

Because the accounting of all sins and the investigation and inquiry about them will destroy and ruin the sinner.

Umm al-Mu’minin Sayyidah Aisha (may Allah be pleased with her) narrates that I heard the Messenger of Allah (peace and blessings be upon him) asking for this supplication in his prayer, «‏‏‏‏اللَّهُمَّ حَاسِبْنِي حِسَابَاً يَسِيرَاً» ‏‏‏‏“O Allah, make my reckoning easy.”Then when the Messenger of Allah (peace and blessings be upon him) finished the prayer, I asked,“O Messenger of Allah (peace and blessings be upon him), what will an easy reckoning be?”The Messenger of Allah (peace and blessings be upon him) said:“The servant’s record of deeds will be looked at and he will be pardoned (for his sins). Because, O Aisha (may Allah be pleased with her), whoever is subjected to a detailed reckoning on that day will be destroyed. And whatever hardship befalls a believer, Allah, the Exalted, forgives his sins through it, even the thorn that pricks him (that too becomes an expiation for sins).”Both narrators have reported the words similarly.

Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates that Sayyidah Umm Sulaym (may Allah be pleased with her) came to the service of the Messenger of Allah (peace and blessings be upon him) and said, "O Messenger of Allah (peace and blessings be upon him), teach me some words that I may recite as supplication in my prayer." He (peace and blessings be upon him) said: "Recite «‏‏‏‏سُبْحَانَ اللَٰه» ‏‏‏‏ ten times, «‏‏‏‏الحَمْدُ لِلَٰه» ‏‏‏‏ ten times, and «‏‏‏‏اللهُ أَكْبَرُ» ‏‏‏‏ ten times, then ask for your need and requirement, and He will say: Yes, yes (your supplication and request is accepted)."

Lady Aisha (may Allah be pleased with her) narrates that I heard the Messenger of Allah (peace and blessings be upon him) say: "You have been shown to me that you are being tested in your graves like the trial of the Dajjal." Hazrat Amrah says that Lady Aisha (may Allah be pleased with her) says, so I used to hear the Messenger of Allah (peace and blessings be upon him) seeking this in his prayer. «‏‏‏‏اللّٰهُمَّ إِنِّي أَعُوذُ بِكَ مِنْ عَذَابِ النَّارِ وَمِنْ عَذَابِ الْقَبْرِ» ‏‏‏‏. "O Allah, I seek refuge in You from the punishment of Hell and the punishment of the grave."

Lady Aisha (may Allah be pleased with her) narrates that the Messenger of Allah (peace and blessings be upon him) used to recite this supplication in his prayer, «‏‏‏‏اللّٰهُمَّ إِنِّي أَعُوذُ بِكَ مِنْ عَذَابِ الْقَبْرِ، وَأَعُوذُ بِكَ مِنْ فِتْنَةِ الْمَسِيحِ الدَّجَّالِ، وَأَعُوذُ بِكَ مِنْ فِتْنَةِ الْمَحْيَا وَالْمَمَاتِ، اللهُمَّ إِنِّي أَعُوذُ بِكَ مِنَ الْمَأْثَمِ وَالْمَغْرَمِ» ‏‏‏‏ "O Allah, I seek refuge in You from the punishment of the grave, and I seek refuge in You from the trial of the Dajjal, and I seek refuge in You from the trials of life and death. O Allah, I seek refuge in You from falling into sin and from being burdened by debt." Lady Aisha (may Allah be pleased with her) says that someone said, "O Messenger of Allah, how often you seek refuge from debt!" So the Prophet (peace and blessings be upon him) replied, "Indeed, when a man becomes indebted, he speaks and lies, and he makes a promise and breaks it."

Sayyiduna Sahl bin Sa’d (may Allah be pleased with him) narrates that there was a dispute among the Banu Amr bin Awf, so the Prophet (peace and blessings of Allah be upon him) was informed about it. He (peace be upon him) performed the Zuhr prayer, then went to them to reconcile between them. Then he (peace be upon him) ordered Sayyiduna Bilal (may Allah be pleased with him):“O Bilal, when the time for Asr prayer comes and I have not returned, then tell Abu Bakr to lead the people in prayer.”So when the time for Asr prayer came, Sayyiduna Bilal (may Allah be pleased with him) gave the adhan, then the iqamah, and said to Sayyiduna Abu Bakr as-Siddiq (may Allah be pleased with him):“Step forward.”So Sayyiduna Abu Bakr (may Allah be pleased with him) stepped forward and began the prayer. During this, the Messenger of Allah (peace and blessings of Allah be upon him) also arrived and, moving the people aside, advanced until he stood behind Sayyiduna Abu Bakr (may Allah be pleased with him). The narrator says that the people started clapping, and when Sayyiduna Abu Bakr (may Allah be pleased with him) started the prayer, he would not pay attention here and there. Then, when Sayyiduna Abu Bakr (may Allah be pleased with him) realized that the clapping was continuous, he wanted to turn, but the Messenger of Allah (peace and blessings of Allah be upon him) gestured to him to continue the prayer. He (peace be upon him) gestured to him to continue the prayer, so Sayyiduna Abu Bakr (may Allah be pleased with him) continued to praise Allah for a while at the command of the Messenger of Allah (peace and blessings of Allah be upon him) to“continue the prayer.”Then Sayyiduna Abu Bakr (may Allah be pleased with him) walked back on his heels and moved behind. When the Prophet (peace and blessings of Allah be upon him) saw this, he advanced and led the people in prayer. Then, when he (peace be upon him) completed his prayer, he said:“O Abu Bakr, when I had gestured to you, what prevented you from continuing the prayer?”Sayyiduna Abu Bakr (may Allah be pleased with him) replied:“It is not befitting for the son of Abu Quhafah to lead the Messenger of Allah (peace and blessings of Allah be upon him) in prayer.”The Prophet (peace and blessings of Allah be upon him) said to the people:“When something happens to you in your prayer, the men should say «‏‏‏‏سُبْحَانَ اللَٰه» ‏‏‏‏ and the women should clap.”In the narration of Ibn Abi Hazim, these words are present: When the Messenger of Allah (peace and blessings of Allah be upon him) gestured to Sayyiduna Abu Bakr (may Allah be pleased with him) in this way and ordered him to continue the prayer, Sayyiduna Abu Bakr (may Allah be pleased with him) raised his hand and said «‏‏‏‏الحَمْدُ لِلَٰه» ‏‏‏‏, then walked back on his heels. In the narration of ‘Abdul A’la, these words are present: When the Messenger of Allah (peace and blessings of Allah be upon him) gestured to him to remain as he was (i.e., to continue the prayer), Sayyiduna Abu Bakr (may Allah be pleased with him) raised his hands at the command of the Messenger of Allah (peace and blessings of Allah be upon him) and praised Allah. Then he walked back on his heels. Imam Abu Bakr (may Allah have mercy on him) says that some narrators have reported additional wording in the hadith compared to others.
