After the last tashahhud and before salam

اللّهُـمَّ إِنِّـي أَعـوذُ بِكَ مِـنْ عَذابِ القَـبْر، وَمِـنْ عَذابِ جَهَـنَّم، وَمِـنْ فِتْـنَةِ المَحْـيا وَالمَمـات، وَمِـنْ شَـرِّ فِتْـنَةِ المَسيحِ الدَّجّال

O Allah, I seek refuge in You from the punishment of the grave, and from the punishment of Hell-fire, and from the trials of life and death, and from the evil of the trial of the False Messiah.

Al-Bukhari 2/102, Muslim 1/412, and this is Muslim's wording.

اللّهُـمَّ إِنِّـي أَعـوذُ بِكَ مِـنْ عَذابِ القَـبْر ، وَأَعـوذُ بِكَ مِـنْ فِتْـنَةِ المَسيحِ الدَّجّـال ، أَعـوذُ بِكَ مِـنْ فِتْـنَةِ المَحْـيا وَالمَمـات . اللّهُـمَّ إِنِّـي أَعـوذُ بِكَ مِنَ المَأْثَـمِ وَالمَغْـرَم

O Allah, I seek refuge in You from the punishment of the grave, and I seek refuge in You from the trial of the False Messiah, and I seek refuge in You from the trials of life and death. O Allah, I seek refuge in You from sin and from debt.

Al-Bukhari 1/202, Muslim 1/412.

اللّهُـمَّ إِنِّـي ظَلَـمْتُ نَفْسـي ظُلْمـاً كَثـيراً وَلا يَغْـفِرُ الذُّنـوبَ إِلاّ أَنْت، فَاغْـفِر لي مَغْـفِرَةً مِنْ عِنْـدِك وَارْحَمْـني، إِنَّكَ أَنْتَ الغَـفورُ الرَّحـيم

O Allah, I have greatly wronged myself, and no one forgives sins but You. So, grant me forgiveness and have mercy on me. Surely, you are Forgiving, Merciful.

Al-Bukhari 8/168, Muslim 4/2078.

اللّهُـمَّ اغْـفِرْ لي ما قَدَّمْـتُ وَما أَخَّرْت ، وَما أَسْـرَرْتُ وَما أَعْلَـنْت ، وَما أَسْـرَفْت ، وَما أَنْتَ أَعْـلَمُ بِهِ مِنِّي . أَنْتَ المُقَـدِّمُ، وَأَنْتَ المُـؤَخِّـرُ لا إِلهَ إِلاّ أَنْـت

O Allah, forgive me what I have sent before me and what I have left behind me, what I have concealed and what I have done openly, what I have done in excess, and what You are better aware of than I. You are the One Who sends forth and You are the One Who delays. There is none worthy of worship but You.

Muslim 1/534.

اللّهُـمَّ أَعِـنِّي عَلـى ذِكْـرِكَ وَشُكْـرِك ، وَحُسْـنِ عِبـادَتِـك

O Allah, help me to remember You, to give You thanks, and to perform Your worship in the best manner.

Abu Dawud 2/86, An-Nasa'i 3/53. See also Al-Albani Sahih Abu Dawud 1 /284.

اللّهُـمَّ إِنِّـي أَعوذُ بِكَ مِنَ البُخْـل، وَأَعوذُ بِكَ مِنَ الجُـبْن، وَأَعوذُ بِكَ مِنْ أَنْ أُرَدَّ إِلى أَرْذَلِ الـعُمُر، وَأََعوذُ بِكَ مِنْ فِتْنَـةِ الدُّنْـيا وَعَـذابِ القَـبْر

O Allah, I seek Your protection from miserliness, I seek Your protection from cowardice, and I seek Your protection from being returned to feeble old age. I seek Your protection from the trials of this world and from the torment of the grave.

Al-Bukhari, cf. Al-Asqalani, Fathul-Bari 6/35

اللّهُـمَّ إِنِّـي أَسْأَلُـكَ الجَـنَّةَ وأََعوذُ بِـكَ مِـنَ الـنّار

O Allah, I ask You for Paradise, and I seek Your protection from the Fire.

Abu Dawud. See also Al-Albani, Sahih Ibn Majah 2/328.

اللّهُـمَّ بِعِلْـمِكَ الغَـيْبِ وَقُـدْرَتِـكَ عَلـى الْخَلقِ أَحْـيِني ما عَلِـمْتَ الحـياةَ خَـيْراً لـي، وَتَوَفَّـني إِذا عَلِـمْتَ الوَفـاةَ خَـيْراً لـي، اللّهُـمَّ إِنِّـي أَسْـأَلُـكَ خَشْيَتَـكَ في الغَـيْبِ وَالشَّهـادَةِ، وَأَسْـأَلُـكَ كَلِمَـةَ الحَـقِّ في الرِّضـا وَالغَضَـب، وَأَسْـأَلُـكَ القَصْدَ في الغِنـى وَالفَقْـر، أَسْـأَلُـكَ نَعـيماً لا يَنْفَـد، وَأَسْـأَلُـكَ قُـرَّةَ عَيْـنٍ لا تَنْـقَطِعْ وَأَسْـأَلُـكَ الرِّضـا بَعْـدَ القَضـاء، وَأَسْـأَلُـكَ بًـرْدَ الْعَـيْشِ بَعْـدَ الْمَـوْت، وَأَسْـأَلُـكَ لَـذَّةَ النَّظَـرِ إِلـى وَجْـهِكَ وَالشَّـوْقَ إِلـى لِقـائِـك، في غَـيرِ ضَـرّاءَ مُضِـرَّة، وَلا فِتْـنَةٍ مُضـلَّة، اللّهُـمَّ زَيِّـنّا بِزينَـةِ الإيـمان، وَاجْـعَلنا هُـداةً مُهْـتَدين

O Allah, by Your Knowledge of the unseen and by Your Power over creation, let me live if You know that life is good for me, and let me die if You know that death is good for me. O Allah, I ask You to grant me fear of You in private and in public. I ask you for the word of truth in times of contentment and anger. I ask You for moderation in wealth and in poverty. I ask you for blessings never ceasing and the coolness of my eye (i.e. pleasure) that never ends. I ask You for pleasure after Your Judgment and I ask You for a life of coolness after death. I ask You for the delight of gazing upon Your Face, and the joy of meeting You, without any harm and misleading trials befalling me. O Allah, dress us with the beauty of Faith and make us guides who are upon (correct) guidance.

An-Nasa'i 3/54, 55, Ahmad 4/364. See also Al-Albani, Sahih An-Nasa'i 1/281.

اللّهُـمَّ إِنِّـي أَسْأَلُـكَ يا اللهُ بِأَنَّـكَ الواحِـدُ الأَحَـد الصَّـمَدُ الَّـذي لَـمْ يَلِـدْ وَلَمْ يولَدْ، وَلَمْ يَكـنْ لَهُ كُـفُواً أَحَـد ، أَنْ تَغْـفِرْ لي ذُنـوبي إِنَّـكَ أَنْـتَ الغَفـورُ الرَّحِّـيم

O Allah, I ask You. O Allah, You are the One, the Only, Self-Sufficient Master, Who was not begotten and begets not, and none is equal to Him. Forgive me my sins, surely you are Forgiving, Merciful.

An-Nasa'i 3/52, Ahmad 4/338. See also Al-Albani, Sahih An-Nasa'i 1/280 and Sifat Salatun-Nabi, pg. 204.

اللّهُـمَّ إِنِّـي أَسْأَلُـكَ بِأَنَّ لَكَ الْحَـمْدُ لا إِلـهَ إِلاّ أَنْـتَ وَحْـدَكَ لا شَـريكَ لَـكَ المَنّـانُ يا بَديـعَ السَّمواتِ وَالأَرْضِ يا ذا الجَلالِ وَالإِكْـرام يا حَـيُّ يا قَـيّومُ إِنِّـي أَسْأَلُـكَ الجَـنَّةَ وَأَعـوذُ بِـكَ مِنَ الـنّار

O Allah, I ask You, as You are the Owner of praise, there is none worthy of worship but You alone, You have no partner. You are the Giver of all good. O Creator of the heavens and the earth, Owner of majesty and honor. O Living and Everlasting One, I ask you for Paradise, and I seek refuge in You from the fire.

Abu Dawud, An-Nasa'i, Ibn Majah, At-Tirmidhi. See also Al-Albani, Sahih Ibn Majah 2/329.

اللّهُـمَّ إِنِّـي أَسْأَلُـكَ بِأَنَّـي أَشْـهَدُ أَنَّـكَ أنْـتَ اللهُ لا إِلـهَ إِلاّ أَنْـت الأَحَـدُ الصَّـمَدُ الَّـذي لَـمْ يَلِـدْ وَلَمْ يولَـدْ وَلَمْ يَكـنْ لَهُ كُـفُواً أَحَـد

O Allah, I ask You, by the fact that I bear witness that You are Allah. There is none worthy of worship but You, the Only God, Independent of creation, Who was not begotten and begets not, and none is equal to Him.

Abu Dawud 2/62, Ibn Majah 2/1267, At-Tirmidhi 5/515, Ahmad 5/360. See also Al-Albani, Sahih Ibn Majah 2/329 and Sahih At-Tirmidhi 3/163.
