أَصْبَحْنَا وَأَصْبَحَ الْمُلْكُ لِلَّهِ وَالْحَمْدُ لِلَّهِ،
لاَ إِلَهَ إلاَّ اللَّهُ وَحْدَهُ لاَ شَرِيكَ لَهُ، 
لَهُ الْمُلْكُ وَلَهُ الْحَمْدُ وَهُوَ عَلَى كُلِّ شَيْءٍ قَدِيرٌ،
رَبِّ أَسْأَلُكَ خَيْرَ مَا فِي هَذَا الْيَوْمِ وَخَيرَ مَا بَعْدَهُ،
وَأَعُوذُ بِكَ مِنْ شَرِّ مَا فِي هَذَا الْيَوْمِ وَشَرِّ مَا بَعْدَهُ،
رَبِّ أَعُوذُ بِكَ مِنَ الْكَسَلِ وَسُوءِ الْكِبَرِ،
رَبِّ أَعُوذُ بِكَ مِنْ عَذَابٍ فِي النَّارِ وَعَذَابٍ فِي القَـبْر.
Aṣbaḥnā wa aṣbaḥal-mulku lillāh, walḥamdu lillāh, 
lā ilāha illallāhu waḥdahu lā sharīka lah, 
lahul-mulku wa lahul-ḥamd, wa huwa `alā kulli shay'in Qadīr. 
Rabbi as'aluka khayra mā fī hādha ‘l-yawmi wa khayra mā ba`dahu 
wa a`ūdhu bika min sharri mā fī hātha ‘l-yawmi wa sharri mā ba`dahu, 
Rabbi a`ūdhu bika minal-kasali, wa sū'il-kibar,
Rabbi a`ūdhu bika min `adhābin fin-nāri wa `adhābin fil-qabr.

We have entered a new day 1 and with it all dominion is Allah's. Praise is to Allah. 
None has the right to be worshipped but Allah alone, Who has no partner. 
To Allah belongs the dominion, and to Him is the praise and He is Able to do all things.
My Lord, I ask You for the goodness of this day and of the days that come after it,
and I seek refuge in You from the evil of this day and of the days that come after it.2
My Lord, I seek refuge in You from laziness and helpless old age. 
My Lord, I seek refuge in You from the punishment of Hell-fire, and from the punishment of the grave.3

1 When you say this in the evening you should say Amsaynā wa amsal-mulku lillāh: "We have ended another day and with it, all dominion is Allah's.
2 When you say this in the evening you should say: Rabbi as'aluka khayra mā fī hāthihil-laylati, wa khayra mā ba`dahā, wa a`ūthu bika min sharri mā fī hāthihil-laylati wa sharri mā ba`dahā: "I ask You for the good things of this night and of the nights that come after it and I seek refuge in You from the evil of this night and of the nights that come after it."
