In the evening:
أَمْسَيْـنا وَأَمْسـى المـلكُ لله وَالحَمدُ لله ، لا إلهَ إلاّ اللّهُ وَحدَهُ لا شَريكَ لهُ، لهُ المُـلكُ ولهُ الحَمْـد، وهُوَ على كلّ شَيءٍ قدير ، رَبِّ أسْـأَلُـكَ خَـيرَ ما في هـذهِ اللَّـيْلَةِ وَخَـيرَ ما بَعْـدَهـا ، وَأَعـوذُ بِكَ مِنْ شَـرِّ هـذهِ اللَّـيْلةِ وَشَرِّ ما بَعْـدَهـا ، رَبِّ أَعـوذُبِكَ مِنَ الْكَسَـلِ وَسـوءِ الْكِـبَر ، رَبِّ أَعـوذُبِكَ مِنْ عَـذابٍ في النّـارِ وَعَـذابٍ في القَـبْر .

…likewise, one says in the morning:
أَصْـبَحْنا وَأَصْـبَحَ المُـلْكُ لله….

‘We have reached the evening and at this very time unto Allah belongs all sovereignty, and all praise is for Allah. None has the right to be worshipped except Allah, alone, without partner, to Him belongs all sovereignty and praise and He is over all things omnipotent. My Lord, I ask You for the good of this night and the good of what follows it and I take refuge in You from the evil of this night and the evil of what follows it. My Lord, I take refuge in You from laziness and senility. My Lord, I take refuge in You from torment in the Fire and punishment in the grave.’

‘We have reached the morning and at this very time unto Allah belongs all sovereignty…’

اللّهُـمَّ بِكَ أَصْـبَحْنا وَبِكَ أَمْسَـينا ، وَبِكَ نَحْـيا وَبِكَ نَمـوتُ وَإِلَـيْكَ النِّـشور .

In the evening:
اللّهُـمَّ بِكَ أَمْسَـينا، وَبِكَ أَصْـبَحْنا، وَبِكَ نَحْـيا، وَبِكَ نَمـوتُ وَإِلَـيْكَ المَصـير .

‘O Allah, by your leave we have reached the morning and by Your leave we have reached the evening, by Your leave we live and die and unto You is our resurrection.’

‘O Allah, by Your leave we have reached the evening and by Your leave we have reached the morning, by Your leave we live and die and unto You is our return.’

اللّهـمَّ أَنْتَ رَبِّـي لا إلهَ إلاّ أَنْتَ ، خَلَقْتَنـي وَأَنا عَبْـدُك ، وَأَنا عَلـى عَهْـدِكَ وَوَعْـدِكَ ما اسْتَـطَعْـت ، أَعـوذُبِكَ مِنْ شَـرِّ ما صَنَـعْت ، أَبـوءُ لَـكَ بِنِعْـمَتِـكَ عَلَـيَّ وَأَبـوءُ بِذَنْـبي فَاغْفـِرْ لي فَإِنَّـهُ لا يَغْـفِرُ الذُّنـوبَ إِلاّ أَنْتَ

O Allah, You are my Lord, none has the right to be worshipped except You, You created me and I am Your servant and I abide to Your covenant and promise as best I can, I take refuge in You from the evil of which I have committed. I acknowledge Your favour upon me and I acknowledge my sin, so forgive me, for verily none can forgive sin except You.

اللّهُـمَّ إِنِّـي أَصْبَـحْتُ أَُشْـهِدُك ، وَأُشْـهِدُ حَمَلَـةَ عَـرْشِـك ، وَمَلائِكَتِك ، وَجَمـيعَ خَلْـقِك ، أَنَّـكَ أَنْـتَ اللهُ لا إلهَ إلاّ أَنْـتَ وَحْـدَكَ لا شَريكَ لَـك ، وَأَنَّ ُ مُحَمّـداً عَبْـدُكَ وَرَسـولُـك .(أربع مرات حينَ يصْبِح أوْ يمسي)

O Allah, verily I have reached the morning and call on You, the bearers of Your throne, Your angels, and all of Your creation to witness that You are Allah, none has the right to be worshipped except You, alone, without partner and that Muhammad is Your Servant and Messenger. (Four times in the morning and evening.)
Note: for the evening, one reads (amsaytu) instead of (asbahtu).

اللّهُـمَّ ما أَصْبَـَحَ بي مِـنْ نِعْـمَةٍ أَو بِأَحَـدٍ مِـنْ خَلْـقِك ، فَمِـنْكَ وَحْـدَكَ لا شريكَ لَـك ، فَلَـكَ الْحَمْـدُ وَلَـكَ الشُّكْـر

O Allah, what blessing I or any of Your creation have risen upon, is from You alone, without partner, so for You is all praise and unto You all thanks.’ ….whoever says this in the morning has indeed offered his day’s thanks and whoever says this in the evening has indeed offered his night’s thanks.
Note: for the evening, one reads (amsa) instead of (asbaha).

اللّهُـمَّ عافِـني في بَدَنـي ، اللّهُـمَّ عافِـني في سَمْـعي ، اللّهُـمَّ عافِـني في بَصَـري ، لا إلهَ إلاّ أَنْـتَ . (ثلاثاً) اللّهُـمَّ إِنّـي أَعـوذُبِكَ مِنَ الْكُـفر ، وَالفَـقْر ، وَأَعـوذُبِكَ مِنْ عَذابِ القَـبْر ، لا إلهَ إلاّ أَنْـتَ . (ثلاثاً)

اللّهُـمَّ عالِـمَ الغَـيْبِ وَالشّـهادَةِ فاطِـرَ السّماواتِ وَالأرْضِ رَبَّ كـلِّ شَـيءٍ وَمَليـكَه ، أَشْهَـدُ أَنْ لا إِلـهَ إِلاّ أَنْت ، أَعـوذُ بِكَ مِن شَـرِّ نَفْسـي وَمِن شَـرِّ الشَّيْـطانِ وَشِـرْكِه ، وَأَنْ أَقْتَـرِفَ عَلـى نَفْسـي سوءاً أَوْ أَجُـرَّهُ إِلـى مُسْـلِم

‘O Allah, Knower of the unseen and the seen, Creator of the heavens and the Earth, Lord and Sovereign of all things, I bear witness that none has the right to be worshipped except You. I take refuge in You from the evil of my soul and from the evil and shirk of the devil, and from committing wrong against my soul or bringing such upon another Muslim.’ shirk: to associate others with Allah in those things which are specific to Him.

قُـلْ هُـوَ اللهُ أَحَـدٌ [ الإِخْـلاصْ ]
قُـلْ أَعـوذُ بِرَبِّ الفَلَـقِ [ الفَلَـقْ ]
قُـلْ أَعـوذُ بِرَبِّ النّـاسِ [ الـنّاس ]
